This person considers any degree outside their personal preference of "important" degrees a pseudo-degree. I am guessing this personal preference probably closely aligns with whatever is currently considered "job-ready" degrees, and ignores the historical context in which some degrees used to be much less valued than presently.

For instance, a degree in math (the M in STEM) used to be considered a dead-end for a job, except to teach primary school, and was very female-dominated. This was true to such an extent that it was women who did most of the ballistics computing during WWII [1]. Many others invented new processes, like Grace Hopper, who designed the first compiler for a programming language. Sometime after the widespread media attention around the first personal computers - and who they were marketed for - this trend reversed, so that by the 1990s computing became seen as a "male" interest, and thus came to be dominated by men. Notably, this media interest was a Western phenomenon, which is why you'll encounter a lot of female Russian or Indian programmers working for American companies that are trying to boost their quotas of "diversity."

Another example of a reversal of trends of "real" degrees is aerospace engineering, a degree which used to be very lucrative (with the end goal working for any of the companies affiliated with the cold-war era space race). But when the United States decided to shut down their space program, a lot of these engineers lost jobs fast, and newly minted graduates could find no work.

If that's all he did, he really wouldn't have been notable enough for Wikipedia. But then he did that thing at the end, so now all the details of his life are just supporting characters to the main story.
