I generally find it unhelpful. People’s reaction time sucks and and so many people hear ‘left’ and jump in that direction before their brain can process. It’s not an intelligence thing that some people try to make it seem, it’s just that the average person has this interaction like once per year thus don’t have muscle memory baked in.
I yell out ‘excuse me’ from several feet back or ring a bell if I’m on a bike. Or more often just slow down as I normally don’t really care.







Pretty much anything about science.
We all know models and simplifications but even the people at the utter cutting edge of any sub-niche of any sub-field you pick will agree there are parts they don’t really understand.
You can master & fully understand sufficiently simplified models but to actually understand the underlying process is to take a step beyond what humanity is capable of.
