Big picture, I'll always believe we dodged a huge bullet in that "AI" got big in a nearly fully "open-source," maybe even "post open-source" world. The fact that Meta is, for now, one of the good guys in this space (purely strategically and unintentionally) is fortunate and almost funny.
AI only got big, especially for coding, because they were able to train on a massive corpus of open source code. I don't think it is a coincidence.
A world without open source may have given birth to 2020s AI but probably at a slower pace.
