The dot com bust was when huge valuations and VC funding was going to companies that had little business plan or even little notion of how to make money. So good advice would be to stay away from those types of companies, regardless of boom or bust. Always have marketable skills and maybe if you are specializing in something now at your job (e.g. front-end JS dev) then make sure your other skills don't stagnate. It seems if there is a 'bust' of some sort it would be more industry specific since there are less companies around trying silly things as their entire business model which is what happened before. I think it would more happen as a slow downturn in an industry rather than a sudden cliff.
