Ask HN: If you had to start a business, what would it be?
Let's say you had no option but to start a business today, what would it be? The only caveat is this has to be your primary income.
All of that capacity has to be built, quickly, with less labor than ever before, with less money as well. Small, efficient machine systems (or retrofit for old machines) that can do job shop work with lights out capability, seem to be a huge growth area.
Maybe a laundromat, self storage facility or mini putt course (in a tourist town)?
