It was a recent time so i doubt much would change, if i had to guess tho

1 - Joe Biden wouldn't be as hated, and could probs actually win 2024 election.

2 - Many things considered "nerdy" wouldn't blow up. Streaming wouldnt be as popular, TikTok probably wouldnt have blown up, prolly would just stay in China. Anime doesn't blow up either.

3 - Economy would be better prolly
