Many are gambles, many are funded by those who know buzzwords but not the actual market or viability. Once that funding runs out, often the buzzword has moved on to something new so no more funding can be gained. You have to find a way to make money without funding in that period. The key issue is trying to grow too fast with too few solutions. If you can solve a problem for people then that is giving you a good chance of survival.
