I think it's unique to tech that people are biased toward thinking things are good just because they're new. I've found that in most of the rest of the world, people think new things are dangerous, frightening, insubordinate, disruptive, and irritating.
I take it you haven't worked at a big company? Companies get big, stakes get high, people get entrenched and complacent--and newness is viewed exactly as you describe.
I have also noticed the 'dangerous/frightening because it's new' bias. I don't understand why it flips one way or the other. People are weird! :)
I voted for Trump, and found my justification after I had decided that I would probably do so. The bottom line was that I wasn't going to vote for Clinton and Trump was the only other viable option.
I've also chosen relatively untested libraries for projects because I'd already used the more mature choice for another project and hated it :)
