Ask HN: Top Skills to Learn for 2023?

I'd add that improving logistics in terms of bundling packages and slowing shipping to handle reduced shipments would do a lot in terms of reducing an ecological footprint (not that I'm big on woke environmentalism).

+1 on reducing options and improving curation... I've gotten in the habit of nearly always selecting "sold by amazon" option in searching... if nothing else, at least the return process is less likely to be a hassle.

I never really bought into the crypto hype... I did setup some bitcoin miners at home to run when idle when it was really early on... I think it was like $0.15-0.25 for a coin in terms of trade value. I had a handful of coins that cost way more in terms of electricity at the time, and couldn't really do anything with them... I deleted all of it off all the machines. Sometimes wish I'd kept the wallets (not sure if Dropbox was around yet) when it hit like $20k or so.

It just feels kind of scammy... but I largely feel that way about the stock market as well.

Learn how to write better. Not code, but prose about code.

I'm not sure how much you know about Elixir, so apologies for stating anything obvious.

* Elixir sits on top of the BEAM (the Erlang VM), which has several decades of being battle tested.

* Elixir is at its core a functional language, with immutable only (not just by default) data, and comes with built-in processes and OTP, a library that provides ready-made abstractions on top of processes. It's very, very good at concurrency.

* Elixir has Mix, Hex, and ExUnit, which provide great tooling and package management.

* Elixir's ecosystem is rather vibrant and active. Phoenix, LiveView, Livebook, Nx, Axon, and more. Elixir generally takes the approach of building things on top of Elixir from scratch, which frees it from having to deal with impedeance mismatches. See Livebook (the Elixir notebook solution) and Nx/Axon, and all the other machine learning stuff going on in Elixir right now.

I highly recommend the presentation The Soul of Erlang And Elixir by Sasa Juric.

It really gets at the core of what makes Elixir and Erlang special, but I'd say Elixir has a lot more quality of life improvements over Erlang.

There's also Charlie Stross (@cstross), from "Dude, You Broke the Future" (2017):

When I write a near-future work of fiction, one set, say, a decade hence, there used to be a recipe that worked eerily well. Simply put, 90% of the next decade's stuff is already here today. Buildings are designed to last many years. Automobiles have a design life of about a decade, so half the cars on the road will probably still be around in 2027. People ... there will be new faces, aged ten and under, and some older people will have died, but most adults will still be around, albeit older and grayer. This is the 90% of the near future that's already here.

After the already-here 90%, another 9% of the future a decade hence used to be easily predictable. You look at trends dictated by physical limits, such as Moore's Law, and you look at Intel's road map, and you use a bit of creative extrapolation, and you won't go too far wrong. If I predict that in 2027 LTE cellular phones will be everywhere, 5G will be available for high bandwidth applications, and fallback to satellite data service will be available at a price, you won't laugh at me. It's not like I'm predicting that airliners will fly slower and Nazis will take over the United States, is it?

And therein lies the problem: it's the 1% of unknown unknowns that throws off all calculations. As it happens, airliners today are slower than they were in the 1970s, and don't get me started about Nazis. Nobody in 2007 was expecting a Nazi revival in 2017, right? (Only this time round Germans get to be the good guys.)
