Because we live in a materialist and incoherent society; from the nihilistic despair of which we crave temporary alleviation - we are continually seeking enjoyable distraction, which is what people seem to mean by "cool".
So if anything is enjoyably distracting it can be termed cool, and this "coolness" is not merely a justification - but actually that which is most-desired, by most people, most of the time.
This applies to our discernment regarding current top-down funded, propagandized, subsidized (perhaps mandatory) societal trends.
It is sufficient justification if we regard as cool phenomena such as Electric Vehicles; a Them-paid-for festival or building art-installation or landscape feature; an "AI" application; a provision or service or activity - or whatever.
It is also cool if some social or organizational change (typically enforced upon us by the totalitarian system, and incentivized for its adoption) offers us a reasonable chance of short-medium term enhanced personal earnings, status, or leisure...
Even when we know that the long-term effect will be destructive of all these...
(After all, people reason; who really knows what the future holds? Maybe everything will be OK? And in the long term we are all dead anyway.)
Coolness evaluations are possible and dominant because very few people nowadays are engaged in any kind of primary-functional activity like raising a child, growing-food, or making/ building/ transporting something genuinely valuable or necessary.
New stuff (discoveries, inventions, technologies, media etc) is therefore judged by very subjective and easily-influenced criteria - and most of the most powerful influences, nowadays, are top-down emanations of the totalitarian system.
So - as well as innovations being top-down devised and imposed; judgements of these innovations are also top-down controlled.
New stuff therefore comes to people pre-packaged as useful and life-enhancing - or even pushed as civilizationally-vital* - on the vaguest of grounds.
(*To which opposition is idiotic or retrograde)
When actually the new stuff is merely cool... at best!
