Have never understood the impulse to dunk on someone trying something new when it does not impact you in any way.

I think it comes from envy? 

Ie, it’s often people who are dissatisfied with their own way, but are too lazy or afraid to try something new

So they try to neg the “impossibility” of change into existence

My theory is it's a cheap (low risk) way to appear smart.

Criticising shit is easy...especially something novel and creative (and therefore likely to fail), so you just pick a thing, critique it, and bank the win of looking smart (and/or "serious").

Far harder, is imagining something new (actual creativity) and then getting it to work.  It's the the realm of consultants.

For me I'm pretty uninterested in the critique of folks who can't ALSO fill the space the criticism creates with some kind of creative alternatives (plural).
