I can assure the author that those of us solving problems for small companies (in terms of employee count, not revenue or assets under management) do not jump on the typical bandwagons. We tend to be very critical and pragmatic.

I'm not even sure it is engineers at bigger companies who choose to jump on these bandwagons. I suspect it is often wannabe-technical managers who read that MegacorpX is using tech Y that sells the idea to upper management, along with some unfounded beneficial promises, that causes some of the trends we see.
