Zig is a simpler language than C and I predict that as LLMs get trained on it more, it will become the best supported low-level programming language by LLMs.

"I wanted to like Zig" (or another language).
Don't 'want' to like Zig. Try Zig out and if it doesn't pan out, go find a different language you can be more productive in.
If you 'want' to like a language, it means that you let hype and marketing poison your reasoning.

For people who heard about Zig just recently:
- Zig is not 2x faster than Rust, despite what recent benchmarks might lead you to believe.
- You won't find many Zig jobs for a few years still, despite the Tiobe stuff.
- Don't join to the Zig community just to rant about Rust.

Everything worked first try thanks to the book being well written, help from chat, and Zig crosscompiling for riscv32 seamlessly.

The Zig project is globally distributed and "work from home" by necessity, while at the same time being one of the most prolific and impactful projects currently active.
But to be fair he was CEO of an advertisement company, can't expect him to know too much about technology.

People on HN are hating on Casey's video about performance while their company is spending double digits % of their revenue on AWS bills to serve 3 forms and 1 database view which took them 6 months to develop using the latest agile methodology.
It also crashes every 24h.

I still cannot believe how people were straight-face telling me that C is simpler than Zig in an earlier conversation. And I haven't even whipped out C macros yet.

People arguing about how OOP is useless with the guy that makes a living selling OOP books and consulting, lol.
People who make a living selling a solution to a problem are always very receptive to mitigations, but are almost never interested in making the problem fully go away.

This is just dumb. Yes, you have to actually know what you are doing, and not just in C++. Also the example is wrong you will not get a heap allocation there. But for a longer string you might.

- How can it be faster than industry standard tools w/ VC backing
- Ok it is faster but it doesn't matter because network latency (LMAO)
- How could it take this long for npm to fetch my deps

Rule #1 when organizing events: if you tell a speaker that their talk was accepted, you don't walk it back. If you tell a speaker that their talk is going to be the keynote, you don't walk that back either.
