Tech has a natural moat in that only a small portion of the population is smart and driven enough to do well in it, so I expect decent paying jobs for the foreseeable future. And while some of high profile startups might have unviable business models, most of the established companies actually have pretty good metrics, so I don't seem them as being in danger of going out of business unless some legislation comes along that completely undermines their ability to do business.

Obviously it's still smart to save and plan for a period of unemployment though.
