Not OP but I believe the main assertion is that Elon Musk's public rhetoric has become increasingly political over the past 5 years and that his dialogue conforms with modern conservative messaging. To break it down:
* Hes posting a lot more
* The content of his posts are proportionately more "culture-war" topics versus company/nerd/geek stuff that he used to post
* Some of his posts align with populist conservative influencers
I don't have data to back this up - just my anecdotal experience.
Well the left side of the political isle has also became increasingly critical of him since 2016 when he briefly worked at the White House. He went from being a darling fighting climate change to an evil villain almost overnight.
I'm about 1/10th of the way through the transcript and I haven't come to this conclusion yet.
