Lex got his PhD at Drexel over a decade ago. If he had pursued an academic career, he would most likely be an associate professor by now. Working as a researcher at a lab at a university that you aren’t a faculty member of is basically “failure to launch” at this stage.
But Lex is a successful podcaster. His dad is a successful academic and scientist (at Drexel.) Lex is not that, but he plays one on the internet.
The rest are at least 6 years old.
So what is he doing as a research scientist. Don’t get me wrong - I like his podcast. I think he gets good guests. But he’s not doing any level of research.
Not just that but I would also suggest to stop using the Internet Archive in general, as it is obviously not a reliable source of truth like Wikipedia or many news outlets with specialized people that spend a non-trivial amount of their time carefully checking all of this information.
