Is bullet chess harmful?


It depends.
I personally never play blitz/bullet right before a serious game, otherwise my mind would be latched on "short term goals" mode

Well the 24-second shot clock ruined "pure" basketball. Too many forced errors.
I miss those 8-6 games!
When Lefty Driesell was coaching Maryland, he got an early lead against heavily-favored North Carolina State and held the ball for something like 30 minutes to win a game with a small score.
Even though I was rooting for the local guys, something wasn't quite right!
