I just imagined a world without noobs where everyone is an expert. There's no room for errors because experts will likely behave like machines. Even experts atimes makes errors or dramatically changes their mind.
It's not about not making mistakes, it's about thinking
before doing something. If you need more than 3 seconds, think for more than 3 seconds. If you can't do that, no amount of popups is going to stop you.
Ok, I understand the logic.
You think before you act, and not wanting a wait time to reconsider your decision after you have acted.
