my one thought is would there be any tricks to get a faster inversion? I bet a lot of conventional things (ode solving for example) would be oom faster if that were the case

AGI is hidden inside the commutative matmul 😔

Also matrix multiplication is intensely symmetric imo, just not in the literal mechanics of how you'd do it by hand

This is such an incoherent take? AI compute is bad because matmuls aren't commutative? If they were, would it be worth it? I don't think this even has its own internal logic

oh I also got better at this over time, but not linearly - probably had my most work centric time ever this past summer

I've ~naturally found I need to build in recharge time for myself if I'm going to be effective at the difficult thinking tasks. So in a way it's the opposite of not having time for hobbies: I don't have the time *not* to do other things, even if the only reason to do them is to be better at science

one of the biggest undergrad to grad shifts for me has been I get fewer useful hours in a day even if I'm nominally working the same amount, and I attribute that to doing more difficult things that need deeper thinking

small group of course, but it's at least true to my anecdotal experience! So what I take away from this is - you don't have to put impossible productivity standards on yourself to be successful. Imo not only does it make you miserable, it doesn't actually work

things take 1.7x as many hours as they think they will and 53% of tasks are completed in the planned week, but the thing I found the most interesting is more senior researchers aren't really better at estimating what they'll get done

so there's this great April Fools paper by @kaleybrauer.bsky.social arxiv.org/abs/2103.16574 that I just used in my welcome-to-grad-school class, where a group of them tracked whether they finished all the tasks on their todo list each week for several months
"I'll Finish It This Week" And Other Lies
A small group of postdocs, graduate students, and undergraduates inadvertently formed a longitudinal study contrasting expected productivity levels with actual productivity levels. Over the last nine ...

You could translate it easily yeah but I don't think it was as intuitive pre digital clocks

I'd bet it's based on analog clocks? You look at the hour hand, it's almost at 2, then you read the minute hand counterclockwise and subtract

yeah the third point is why I haven't been able to share his work in relevant discussions - I like the conclusions if true, I just can't rely on the chain of logic that gets there
