Stereolithography is horizontal, one layer at a time, and uses photopolymerization (that's Formlabs). (Also Digital Light Processing is close but distinct: https://formlabs.com/blog/3d-printing-technology-comparison-...)
Continuous Liquid Interface Production (CLIP) also uses photopolymerization, but pulls the object from a liquid bath and uses a buffer zone. Still horizontal slices. The upshot is it's much faster. (Carbon 3D is the company behind this.)
The method in the article uses photopolymerization to solidify the object as a set of slices, but the slices are not horizontal.
The big drawback to photopolymerization is it only works on certain resins which can often have undesirable mechanical properties (high elasticity or brittlness, for e.g.) Potentially this method could be a way forward in that respect, because you might be able to put structural materials in the resin solution and end up with a composite. It seems easier to do this way than with CLIP or SLA/DLP, but I'm purely speculating.
Weird comparison since Apple has always made the lion’s share of profits from hardware. Also interesting contrast between big automakers and Tesla. I see Tesla as being in the hardware biz primarily
As I write, I realize this must have been tried somewhere. I know at one point Sandia Labs allowed employees to start spin-offs using tech developed there, but that's not quite the same.

Okay then. Let's go beyond games already!
He gives one definition that people have used before, about unaided machines performing every task at least as well as humans. But if you dwell on it a while, I'm sure you can find lots of disagreement about a) what that looks like and b) whether it is true or not (conditional on it being true to at least someone.)
It seems the Ainu are considered indigenous because some have maintained their culture instead of assimilating into the larger group, which is unlike the Jomon and Yayoi people who many believe are the ancestors of modern Japanese people.
The insights designers get from just watching someone use a product are always delightful. The idea is basically ethnography for design. (https://www.interaction-design.org/literature/book/the-encyc...)
'Desire lines' in parks are one example. Desire lines are the paths in the grass that get worn down because people use them even though the designer didn't plan for it.
I have a friend who makes rock documentaries and his boss will often rent an $8K camera. My friend sometimes shoots on a $500 DSLR, and once mixed in some of his footage. His boss could tell the difference, but it wasn't significant, and it made him wonder why they even rented the nicer camera.
I'm not saying it isn't true, just that this evidence is weak.
> this “aesthetic” courtship, says Prum, creates an environment, temperaments and rituals — a sort of culture — that give the female sexual choice, autonomy and safety
Maybe natural selection at a species level (notice the word 'safety') selects for individual-level sexual preferences? If that is true, the theories aren't substitutes, but complements.
Again, maybe I'm just lost.
> millennials, who, as it turns out, are not a monolithic generation
Then, I feel they go right back to the attitude in a new context:
> Yet millennial suburbanites want a new kind of landscape.
I'm interviewing for jobs (finishing phd) and our income/cost ratio will hopefully increase, and I think we'll end up in a place with more space. But I don't have the experience to have calibrated to the exact amount of space I'll need. We'll probably overreact and be gluttons for space. Then we'll fill up the excess with stuff.
I don't know, maybe I'm wrong. It just feels like you want space, then you get it, then you fill it with stuff you don't want.
The reasoning is almost entirely post-hoc. He observes many successful people and their similarities and then claims "I have now told you how to succeed." p(success | trait) != p(trait | success). Hindsight bias is at play.
He makes other weird statements: "you are automatically condemned to waste the rest of your life (see Einstein above)." Mr. Hamming is a difficult guy to please.
Mihaly Csikszentmihalyi studied many successful individuals in a systematic way and acknowledged the inherent problems with this approach. Read his book instead of this: https://www.amazon.com/Creativity-Flow-Psychology-Discovery-...
Finally: "Those who have done really great things generally report, privately, that it is better than wine, the opposite sex, and song put together."
This is strongly contradicted by Mihaly Csikszentmihalyi's evidence. Nearly everyone he talked to (many Nobel Laureates among them) said their greatest achievement was raising a family or something in personal life. I can't claim this generalizes, but I can provide it as a stark counterexample to Hamming's claim.
My theory derives from these sources: https://www.economist.com/news/books-and-arts/21695371-theor... (Chomsky's recent theory of how language evolved has not been accepted favorably), and
