When the company you work for is burning VC money with no hope or intention of profitability, the only rational technology choice you can make as an engineer is to pick a promising but unproven technology which could boost your resume and help you land your next gig more easily. Or you simply pick it because you like and want to work with it and there is no one to stop you.

I'd be very happy to hear I am wrong about this and see a profitable company with an established product using it.
