I'd say with no actual data to back up my position, that it is increasing.

My reasoning would be because tech companies have designed social platforms to reward shallow hot takes. If you say something provocative in the fewest amount of characters you generate the largest response. You are rewarded with karma/likes/votes/retweets. This we all know fuels dopamine reaction so it creates a cycle.

Short hot takes need to maximize the provocation of the statement. These short comments are easy to share and digest which is easy to create a short response towards.

Doing this over and over you have to devolve into crazy ass statements that resemble something a sociopath would say.
