>Also consider games, back then one or two guys could do a game, now all but the outliers are done by large teams.

If anything the opposite is true. Gamedev tooling is now so good and high level one or two people can make sophisticated games, in terms of audio, gameplay and visuals that an entire team could not make in the 80s or 90s.

Just one example, Signalis (https://rose-engine.org/signalis/). One developer and one artist if I'm not mistaken, stunning game that in say 2000 would have been a release from a major publisher.
