I think you’ve also gotta be comfortable being in a pretty dark place a lot of the time.
It’s like being a plumber if your tools did surprising things or simply broke and required repair regularly, you had to learn totally new (and usually not any better) tools every year or two, and you did the actual work with a crappy remote-control robot, mostly crammed into dark spaces, with no schematics or plan or even ability to personally see the outline of the general area you’re working in and lights that only illuminate about 2 feet ahead.
Lots of the time all your shit you need to do the other shit is broken or is lying to you, and you’re also in some awful little mess that you can’t be sure there’s any real way out of because you can’t goddamn see anything.
“Ok time for standup!” now try not to slip and say “fuck everything, I hate life, all of this is bullshit and I’m pretty sure we don’t even need to be doing it. No blockers.” Keep on your mask that presents you as employably-stable.
It kinda fucking sucks. I get why people don’t want to do it.
[edit] oh and it’s that plus all the usual offices-suck dehumanizing , quietly degrading, pointless-feeling, politically- and ethically-nasty (cf Moral Mazes), boring shit that people’ve complained about in much the same way since the 50s or so (e.g. Yates’ Revolutionary Road)
