the first two computers were connected in 1969 leading to arpanet. I would say the qualitative experience took quite some time to improve. The type of algorithms ai has evloved from I would say came out of the 2000’s maybe late 90’s. Taking google as sorta a baseline maybe. I would say we are equivalent now to about mid nineties internet wise so it will be interesting to say the least on where this goes. They do use to much energy though and I hope they can bring this down maybe with hardware acceleration.
