Last thing I saw Karpathy talk about was this, which I find hard to believe that it came from a smart person.

REPL-based workflow doesn't make sense to me other than scripting work.

rust-analyzer is a great LSP and paired with clippy it can teach you the language itself. Also, writing numerical code is extremely easy in Rust. I can write code and just run cargo run to see the output. Julia, on the other hand, forced a REPL-based workflow which never has made sense to me. REPL-based workflow makes sense when you just want to do some script stuff. But when writing a code which will run for a long duration on a HPC? I don't get it. Part of the problem is I'm not "holding it correctly", but again, out of the box experience isn't good. You define a struct and later add or remove a field from it. Often you'll get an error because Revise.jl didn't recompile things. It was a sub-par experience and I was hoping to people would share their dev workflow in more detail

To those who regularly write Julia code, what is your workflow? The whole thing with Revise.jl did not suit me honestly. I have enjoyed programming in Rust orders of magnitude more because there's no run time and you can do AOT. My intention is not write scripts, but high performance numerical/scientific code, and with Julia's JIT-based design, rapid iteration (to me at least) feels slower than Rust (!).

There's a lot of useful advice here that'll surely come in handy to me later. For now, yeah I'm just going to try to make things work. So far I have mostly written intra-node code for which rayon has been adequate. I haven't gotten around to test the ergonomics of rs-mpi. But it feels quite an exciting prospect for sure.

Also what benchmark? How will you you design it?

For now my plan is to write fairly similar style code as one may write in C++/Fortran through MPI bindings in Rust.

Because passing pointers isn't as ergonomic in Rust, I do things in arena-based way (for example setting up quadtrees or octrees). Is that part of the issue when it comes to memory bandwidth?

None of this is equivalent to the topic of discussion. The point is that even in a world of division of labour and shared expertise, there is no atrophy in general populace because someone is trying to become expert in something. The whole point is that the brain is being put in use to do something. If not in X, then in Y. If none of the alphabets are available, where do you put your brain in use to?

>I would not assume someone who won the lottery is going to have their life become uninteresting or see some cognitive decline. It could probably happen, but you can also see a path where the person just chooses to do the activities they always wanted to do, where they keep learning and exploring without the burden of usual life constraints. People already play chess when machines have beaten us for decades, just because they enjoy it.

Again, please play attention to the main idea of the article linked. Most of cognitive development happens in the early formative years. Yes, learning itself never stops, but the primary period of it during perhaps the first 25 years of someone's life. You NEED to make mistakes and learn from them during this period. If you are offloading work that your brain was supposed to do here, it's extremely worrying.

>Regarding education I think AI is a huge revolution waiting to happen. Usual courses have become boring? Have future super powerful AI generate per student highly personalized programs, create bespoke video games where succeeding can only happen once the student has validated all the notions you wanted them to validate etc.

I think there is some truth to it, but you need to regulate how much AI can assist a student. It can be a patient teacher but it shouldn't replace their cognitive abilities. That is the whole point.

Children learning in schools should not become product managers. If they are, what exactly is the "product" that they are "managing"? Reducing everything to and looking everything from a corporate viewpoint is bizarre.
