You can get a massive performance penalty if your code does not take into account store forwarding. x.com/i/article/2118…

Loongson processors have 16-byte SIMD (LSX) and 32-byte SIMD (LASX). The simdjson library supports both, but we disable the 32-byte variant by default because it is slower.

Your economy is downstream from tech culture.
Back when I was a kid, I got a TRS-80 computer. It came with a great book about programming, so I taught myself to program.But where could I go? It would be years before I found that there was a local computer club. And it was small, mostly one guy who acted as the leader.And, unsurprisingly, a software industry never came.
Naively you may think that the web solves the problem. A kid in the poor village in India has access to Reddit and everything else. It is a mistake many politicians made at the beginning of the 2000s. They thought that the web meant that any backward place could become a tech player.The problem is not the place, but rather the people.
To be fair, you can connect with the right people and absorb the right culture wherever you are in the world... the Internet is a blessing in this sense. However, once you turn around and go talk with the people you need to interact with... you may simply not have the means to communicate your ideas. There are just too few people with your tech culture.
It is unclear to me how AI is going to impact this effect. Will we see more geographic diversity?

I attended VCF Montréal 2.0 (Vintage Computer Festival) this afternoon. I missed @davepl1968 who was a speaker. I was told that he was a few meters from me.
Met with @cjauvin. I got to discuss old computers. I somehow thought that most processors from era in home computers in North America were from Motorola. It is wrong, but not entirely wrong, they were from MOS and MOS was started by engineers from Motorola who simplified the designs. In the UK and Japan, Zilog was popular, Zilog came from Intel folks.
The talk by @caboken, Roberta Williams and @allowe was inspiring.
