> This is spot on. My dad was a professor and had dozens of PhDs. The only thing differentiating them (as I remember him telling me) was the resolve to keep work as /tiny/ as possible. Who is remember for his/her PhD? Only the smallest cream of the crop. He even made good fun of worthless thesis by (then) well known professors. It’s not about your PhD.

My professor once told me he presented at a small conference, the whole audience everybody had PhD in mathematics and maybe 2 of the 50 or so people in the audience could follow along. The point he was trying to make is at some point the people in the audience were not really interested in what was being presented because it is difficult to just follow along some really niche topic.
