To that last point; it is impossible to understate how fundamentally important Nvidia's Pascal architecture has been to the development of both gaming and AI. In my mind, its the most important computing chipset invented in the 2010s, and belongs among the "world's greatest" chips next to the Intel Core architecture, Apple's A-series, Pentium, and the 8086. It put Nvidia, quite literally, 5 years ahead of the competition almost overnight; AMD is still catching up, three years later, to the perf-per-dollar and perf-per-watt of the GTX 1080.
That chipset, and the cards that were made with it (GTX 1080/1080Ti namely) were the first indication that DC rendering with a stream-to-client architecture was actually possible for video gaming. Before that it was hard to make an economic case for it.
OnLive was purchased by Sony, and its easy to conclude that they repurposed their tech for their Playstation Now service. So it lives on.
