It stands to reason therefore that the people who remain online to comment may have lower levels of mental hygiene by virtue of their ongoing exposure to the internet and social media, thus resulting in a gradual decrease in sentiment over time.

We have some experience now how technology created a lot more problems where we rushed into solutions without thinking of the consequences. It's experience based technoscepticism.
If social media could can polarize countries, imagine what a readily available reasoning engine can do.
The negativity in tech is largely scapegoating driven in my opinion. The slanderers behind the non-existent 'Techlash' haven't stopped any more than the idiots trying to ban actual non-backdoored cryptography. It is all so incredibly stupid to me yet people keep on falling for the crap often enough that I disengage with them entirely. And people basically look at me like I'm the crazy one for pointing it out.
