honestly cs job market is cooked—you send 1,000 applications and get 3 callbacks, it’s just over. if you actually still want a cs career without already being credentialed you have to probably network & get a gig at startups, not even sure what else you’d do.

the biggest companies to be built over the next decade will be in aerospace & defense. but most modern SaaS can't be used due to ITAR export restrictions and data security concerns (eg. Slack, Deepnote, etc.). [x] for aerospace & defense might be a place to build a big company.
