> In my view a spinor is even more familiar than a vector

Okay... Pauli and Dirac both received Nobel Prizes for discovering spinors. Nobody needed to discover pointing in some direction.

Same. I rarely use mine and find that they just about always still have battery. And even when they don't I'll just plug them in and go find something else to do for a few minutes and by the time I come back they are usable for hours. The talk about the power button is super strange to me.

> It fixates on one particular basis and it results in a vector space with few applications and it can not explain many of the most important function vector spaces, which are of course the L^p spaces.

Except just about all relevant applications that exist in computer science and physics where fixating on a representation is the standard.

> I own an M4 iPad Pro and can't figure out what to do with even a fraction of the horsepower, given iPadOS's limitations.

Literally everything you do gets the full power of the chips. They finish tasks faster using less power than previous chips. They can then use smaller batteries and thinner devices. A higher ceiling on performance is only one aspect of an upgraded CPU. A lower floor on energy consumed per task is typically much more important for mobile devices.

The difference in usefulness between ChatGPT free and ChatGPT Pro is significant. Turning up compute for each embedded usage of LLM inference will be a valid path forward for years.

That's a JIT. It uses the same compiler infrastructure but swaps out the AoT backend and replaces it with the JIT backend in LLVM. Notably, this blog post is targeting on-device usage which a custom JIT is not allowed. You can only interpret.

Because the usefulness of an AI model is reliably solving a problem, not being able to solve a problem given 10,000 tries.

Claude Code is still only a mildly useful tool because it's horrific beyond a certain breadth of scope. If I asked it to solve the same problem 10,000 times I'm sure I'd get a great answer to significantly more difficult problems, but that doesn't help me as I'm not capable of scaling myself to checking 10,000 answers.

Without reading an entire novel's worth of text, do they explain why they picked these dates? They have a separate timeline post where the 90th percentile of superhuman coder is later than 2050. Did they just go for shock value and pick the scariest timeline?

Only gripe I have with the tool is that once you've gotten a country right a few times it zooms in too far. I still had no clue where Eritrea was after getting it right like four times. Just got lucky.

But now that the map only shows me three possible countries I can trivially remember which one it was. Ask me again tomorrow while only showing me the full map and I might guess it's in South America.

To not lose. History is full of stories of incumbents not wanting to cannibalize themselves and dying because of it.

> Nobody up to this day has been able to give a formal mathematical definition of intelligence, let alone a proof that it can be reduced to a computable function.

We can't prove the correctness of the plurality of physics. Should we call that a dead end too?

> The argument is that, instead of hiring a junior engineer, a senior engineer can simply produce enough output to match what the junior would have produced and then some.

...and that's just as asinine of a claim as the original one

When shopping for a new car to take to the race track on the weekends did you stop and point out that the Honda Odyssey's suspension is too soft?

I guess this is the new "Be maximally evil" Google. Visual ads while driving that force you to look at your phone.

Ditto. They'll use it now while they stand to benefit and in 3 years they'll be lambasting OpenAI publicly for not being private enough with data and pretend that they never had anything to do with them.

If you're measuring a compiler you need to post the flags and version used. Otherwise the entire experiment is in the noise.
