It’s time to call yesterday the beginning of the endgame.
Midgame lasted about three and a half years. Needed new skills and few succeeded, but those that did won big.
Bases are built out and tech is already advanced but the biggest discoveries are at the end of tech tree.
Stakes are the highest ever and competition likely will be the most brutal here.
It is the end of the beginning. I’m fairly certain ChatGPT signifies beginning of the midgame. Usually skills required to succeed in midgame are different from the early game.
