I've more or less come to a pretty similar conclusion. I wouldn't characterize it as evil per se, but it's a fools errand at best. My line of thinking goes somewhat like this - before the Neolithic revolution humans had an extremely small set of problems. The main problem being "what am I going to eat?", and to a large degree, life must have revolved around this problem almost entirely. There weren't that many people, there weren't that many problems, we somehow persisted in that state for hundreds of thousands of years with literally nothing to write home about. Any advance in technology has literally been trading one problem for at least three more. Now there are loads of problems, loads more people, and the standard approach to solving all the problems is to invent new technologies, which in practice seem to actually exacerbate the problems. So, I just sort of view the current state of things as "somewhere around the turn of the Neolithic Revolution we took a wrong turn, and it has widely been regarded as a bad move."
It's a weird sort of defeatist, nihilistic, melancholy worldview, but to be honest, I don't think we're wrong. I mean... what's the endgame of technology?
