While Zuck's contributions are probably overwhelmingly more negative than positive, Meta initiated both pytorch and llama which have had profoundly positive effects on AI research. And I really am not a fan of python :D
pytorch is really mostly C++ after all, you don't have to use it with python.
Python just allows you to use it like "normal code", whereas if you program it in C++ you really get exposed to what's under the hood and can't write "normal code"
Yes, but have those positive effects on AI research had a positive or negative effect on society? I guess time will tell
Wasn't LLaMA or Llama 2 the first ever open weight LLM through a leak, and weren't there speculations that Zuckerberg himself might be involved in it? He does seem like a good-ish guy at the most crucial moments of truths.
