More surprising to me: Xerox patents were allowed to expire. What I draw from this is that when patents are allowed to work as intended[0], that corporations are very much more likely to invest in new technologies and push for new innovations. They were able to still reap billions off the printer market they invented, but this seems to have kept them on their toes, founding PARC, which inspired / lead to tons of innovation in its own right (even if it wasn't owned by Xerox).

I know this isn't the direct point of the video, but that is my ultimate takeaway here, that the patent system, when applied as intended[0], actually drives innovation and reasonably protects innovators long enough for them to make enough to fund their next thing etc.

[0]: Approximate definition I mean of this: Giving the inventor(s) the monopoly on a technology / innovation for a finite period of time, then released into the public domain

edit: apparently I got my facts wrong (took video at its word that the patents expired) but that is, in fact, not the whole story. Though, I think my broader point is still sensible, that a functioning patent system, when working as intended, would foster innovation & investment that otherwise wouldn't be fostered.
