I'm at a bootstrapped company that was profitable since inception, so we're relatively safe in the event of a collapse in VC funding.
My concern is that, as far as I can tell, almost all bootcamp-trained coders are going to VC-funded startups, many of which are fairly early stage. Those jobs could all disappear overnight, so to speak, if a bunch of VCs decided they wanted to invest their money in something other than technology.
