I don't know. If I were young and single and fresh out of college with a six figure job offer at a San Francisco company, I would consider this, at least until I got my footing.
Sure, it might suck, but I could put up with a lot of suck in order to be able to pocket that much spare cash.
I'm very far away from "young," but I was once. Even in my early 20s, this would have seemed terrible. Sure, you have access to an interesting city, but you have no space for anything you can call your own. Even a rented studio anywhere else gives you somewhere to have a home you can call yours.
Most of the people living in these pods are startup founders, so it makes sense for them to live in shitty pods next to their potential clients and investors.
btw The positions you could use are pretty limited because of the small space. Would you support it from underneath? Missionary? Superman? And what do you do with the waste materials. Are you free later?
700 a month !? It's cheaper to live in a cube hotel in cyberpunk red (the ttrpg), and the room is even bigger (I mean, not much, but at least the bed can fold and you can have a table, and even a chair, during the day)
