Smartphones are probably the ultimate computing device, for reasons of human physiology
In the most recent episode of The Talk Show, John Gruber and MG Siegler agreed that the smartphone will be difficult to overthrow as the dominant method of computing. Something unthinkable would need to happen for us to leave the phones at home in favor of watches, earbuds or pendants, Her-style. So, even if SoC and batteries improve to such extent that we could fit the 2040s equivalent of an M5 chip into a MacBook, iPhone and AirPods equally, and all with great battery life, people would still reach out for their phones first.
This wasn’t the first time I heard the thesis, and it always sounded about right. I don’t know about everyone else, but I tend to be impatient when chatting with Siri. This isn’t about its “lack of” intelligence: although I had only used ChatGPT’s voice chats as a novelty when demoing it to elderly family members, even they needed a few more seconds to answer specific questions than my patience would allow. So why is that?
Well, my impatience would suggest that bandwidth is key, more specifically our own bandwidth to process information. Humans are visual creatures: much of our own brain’s neural pathways are tied up in receiving and processing information from the 6 million cones and 120 million rods contained in the approximately 2,200 square millimeters of our retinas. The next sense down in the number of receptors is not even close: touch, with about 4 million somatosensory receptors packed in the average 1.79 square meters — or 1.79 million square millimeters — of body surface area. That is two orders of magnitude more sensors packed into three orders of magnitude less space in retina (sight) versus skin (touch). What about sound, which is competing with sight as the interface of record? There are around 15,500 hair cells in each cochlea for 31,000 total — not even close. [Note: This is why writing has been the defining achievement of our species, condensing the ineffable into something we can quickly process, and why I will never get tired of reading histories of notebooks and paper. ] But you don’t need to know any of this to have experienced dreams. When was the last time you remembered a particularly nightmarish smell or sound when you were asleep?
So if the optimal way for computers to communicate with us is via retinal inputs, does it not make the most sense to attach most of the local computing machinery onto the interface?
But what about our outputs? Unless you were born on Krypton one wouldn’t expect anything shooting out of your retinas to interact with the environment. Well, here is my main uncertainty in the smartphone-as-the-ultimate-device hypothesis: could you not, on an infinite timescale, wear contact lenses that could beam in information to you as efficiently as possible? Are the Apple Vision Pro and whatever creepiness Meta is out with now not steps towards our corneal computing future? Perhaps, but perhaps not, and the interaction with whatever is beamed into our eyes will be the next limiting factor.
All our movements are planned in the prefrontal cortex and executed in the precentral gyrus of the frontal cortex. A lot of that surface area is dedicated to our hands, as the creepy but to the best of our knowledge accurate cortical motor homunculus shows. [Note: Fun fact about the brain: it’s plastic. In that, it can and does get rearranged as circumstances warrant, and the extent of the rearrangement can be drastic. But receptor numbers are what they are, so any broad changes to the general population would have to take… millennia? Dozens of millennia? Certainly longer than the life span — not to mention attention span — of the average S&P 500 company. ] The side by side representations of the sensory and motor homunculi twins is particularly striking in showing how important our hands are to our sense of self. Now, another prominent feature they have are large tongues and lips, much of it in the service of producing sound, so it is not a surprise that voice controls exist, and not just for the times when our hands are otherwise occupied. Yet what the homunculi show and what any cat parent will attest is that humans are, to the outside world, mostly a pair of hands attached to some rather bizarre squishy elements. Hey, we may as well own it!
The most serious consequence of this state of affairs, much to my disappointment, is that smartphones as we know them are here to stay so there isn’t much point in hobbling my own computing experience with black and white displays, “feature” phones and the like. While I would have loved, in my project to ditch Apple, not to replace my iPhone with anything else “smart”, reason says to try and find a true alternative. GrapheneOS looks promising, and by the time my current phone kicks the can or passes on something else may come along. Here’s hoping.
As promised, today’s update to Microbe — a micro.blog client for Emacs now at version 2.0 — includes draft syncing. There were also some minor updates to Inkling. Both are available on GitHub though I think I’ll just drop that and just host them here. Something to think about for next week…
Well, folks, I did it: I have hit FeedLand’s feed creation limit. Any chance this can be increased, @dave? I’ve just discovered a new blog I’d like to add.
Behind every human success story lies a billionaire with a heart of gold
I tend to avoid podcasts in the style of Joe Rogan, those that begin with a 15-minute long ad block selling mushroom supplements followed by hours of meandering conversation between two people who may or may not be under the influence. Who in the world has the time?
So for that reason I avoided the podcast of one Dwarkesh Patel even as I occasionally linked to an article of his. I filed him mentally in the same “Avoid!” bucket as Lex Fridman — probably unfairly, as no one in the world can be as big of a mental bore as Fridman — without giving his podcast a chance. Although, judging by his writing on AI, I would not have liked the tone even if I had heard it. I remember, in fact, resisting the temptation to pan some of his more outlandish texts prophesying the rise of our LLM overlords with a tone which was as matter-of-fact as it was uncaring about human culture and society. My headphones are a direct link to my brain and I did not want that kind of world view to influence it.
Well a whole bunch of people are about to get influenc’d, because the New York Times has just published a glowing profile of Patel and his podcast, framing the show as a way to “eavesdrop on the A.I. elite” while burying an important fact — the one that kept me from listening in the first place — in the fourth-to-last paragraph:
Mr. Patel doesn’t see himself as a journalist, and he will do things that news organizations’ ethics rules generally prohibit, such as signing onto an amicus brief on behalf of Anthropic in its recent lawsuit against the Department of Defense, and angel-investing in companies whose founders he has interviewed (he disclosed the stakes). He believes in a “glorious transhumanist future,” and his tone isn’t adversarial. But his admirers say that his technical fluency and extensive preparation enable him to follow up or push back on superficial answers that most interviewers would simply accept. The Jensen Huang episode became heated as Mr. Patel repeatedly challenged the world’s most valuable company’s chief executive on the national-security implications of selling chips to China. “If I do cover a topic,” Mr. Patel says. “I think my reputation would suffer a lot if I don’t ask tough questions or don’t do it in a deep way.”
Of course, praising for this kind of pushback on a transhumanist podcast is like praising the host of “The Ultimate Potato Chip Podcast” for pushing back against Frito-Lay’s most recent price hike: it goes without saying that you like junk food.
But it was not this small bit of confirmation bias which made me link to the NYT. Rather, it was the same revelation that piqued Tyler Cowen’s interest, if for a different reason. Rather than paste the whole excerpt, let me provide a (human) summary: bored during the covid pandemic, a 19-year-old Patel asks the libertarian George Mason economist Bryan Caplan to be a guest on his brand-new podcast; Caplan agrees. They continue the exchange, online and in person, while Caplan is spending months in Austin, TX at the home of his billionaire friend Steve Kuhn. [Note: This wasn’t the only good billionaire-themed article in the NYT. For more reasons why Americans should probably do a bit more to clip their wings see the travails of one Sergey Brin and the series of hardships he endured that pushed him to the right. ] Kuhn also meets Patel and, liking the cut of his jib, offers to invest in return for equity. So do other people in the Caplan-Kuhn circle which inevitably expands all the way to your friendly neighborhood founder of Amazon. Cue NYT’s signature glazing.
Crikey. Fans of C.S. Lewis should recognize immediately the themes he raised in The Inner Ring, The Abolition of Man and That Hideous Strength, essays and books which were most likely not on Patel’s reading list during his formative years. One can only wonder whether his belief in “the glorious transhumanist future” came before or after the Silicon Valley billionaires made landfall in his young mind.
Monday links, in concurrence
- Cory Doctorow: The enshittification multiverse, in which Doctorow proposes a general theory of enshittification to match his initial, special theory. I enthusiastically concur.
- Anonymous on the Marginal Revolution comments section: On health care price transparency. The only non-Xified content you can find on Marginal Revolution these days is in the comments, so I am glad that Cowen highlighted this minute dissection of the madness called American medical billing. Needless to say, I concur.
- Reese Richardson: A do-or-die moment for the scientific enterprise. [Note: ᔥAndrew Gelman, who sure loves his mile-long headlines. ] This is the author’s summary of a more detailed paper in the academic journal PNAS which points to a looming catastrophe of LLM-boosted scientific paper mills holding hands with pliant journal editors to decimate the signal-to-noise ratio of the literature. Of course I concur!
- Cory Doctorow, again: Ada Palmer’s “Inventing the Renaissance”. His review after actually reading the whole book, and yep.
All I can think of while reading Nilay Patel’s software brain essay, quoted and linked to all over the web, is the slight but dense Metaphors We Live By. Software databases — metaphoric file cabinets and manila folders — now themselves becoming metaphors for physical objects is truly Escherian.
Another weekend, another free hour to improve Inkling, the 95% Gemini-generated Emacs client for Inkwell. In addition to fixing a couple of annoying bugs — and how great is it that every RSS feed is its own unique snowflake? — I’ve added a bookmark manager for micro.blog’s bookmarks, complete with tagging. Next up: adding drafts to Microbe.
📚 Currently reading: "Inventing the Renaissance" by Ada Palmer
A mere 50 pages in and I can already tell that Inventing the Renaissance will be a banger of a book. Three concepts in particular stood out for there relevance far outside that particular period in history:
- Legitimacy, why it is important to have it and how to obtain it. Marrying into a noble family, graduating from a well-known program, surviving a few years in big pharma/big tech, getting linked to by a major website, etc.
- Zombie ideas as wrong theories that lead to more research that leads to correct theories but then refuse to die — cruthes that outlive their usefulness. See also: zombie medicine.
- Conflicting projections, as in the Medicis playing to role of “merchant scum” in Florence, a city which tends to banish people with ambitions towards nobility, while at the same time playing up your high status to the outsiders who view symbols of nobility as a sign of legitimacy (see above). It is a tough game to play which is why the AI companies are failing at it so spectacularly (to investors and eneterprise clients: we will eliminate the need for XX% of the work force; to the plebs: let us build data centers, it will create jobs; to themselves: why do they hate us?)
No surprise that it has been nominated for a Best Related Work Hugo Award, and kudos to Palmer for compelling me to write the first “currently reading” post in almost two years (the last one was also for a book she wrote).
🕹️ Good write up in today’s FT about Esoteric Ebb, a fantasy RPG which seems to be heavily influenced by Planescape: Tornment, Disco Elysium and Terry Pratchet’s Discworld. Sign me up! Mentioned at the end is Type Help, a free-to-play text adventure that is quite unlike any work of interactive fiction I’ve seen before. Recommended.
Thursday links, let's put a number on it edition
- Subscription Cost Visualizer [Note: ᔥSwiss Miss ] , a nifty online tool that is like DaisyDisk for your subscriptions. Wish I had it before the purge for a before and after.
- Joan Westenberg: Why prediction markets are a sure sign that our civilisation is in decay. The only nit I have to pick with this marvelous essay is that Westenberg mentions Nate Silver, he of old 538, as “one of the more honest figures here” without mentioning his clear conflict of interest.
- David Cain on Raptitude: Count Your Blessings, but Count Carefully. A nice reframing of the human condition, which I will add to my list of mental models.
- Peco Gaskovski: Measuring out my life in coffee spoons. The me with and without coffee are indeed a different person, and anyone with whom I’ve crossed paths owes some gratitude to the Ottomans for bringing it to Europe.
- Daniel Franks: on Yi Yi, my favourite movie and why I think everyone must watch it. I am yet to see it, but it is on the list!
