However, if you yourself are so dedicated to pursuing mathematics (which does sound like an interesting topic) know that there are mathematicians in industry. Tech companies and government agencies hire huge numbers of math majors, and although the work can stray into the realms of applied mathematics, your interest in pure math could serve you well.
And in order to do interesting mathematical work in industry, you have to have a PhD and therefore you must again be placed in the extremely competitive and toxic environment of academia. And regardless, any theoretical knowledge of pure math would be unnecessary due to the existence of these libraries that basically do all the thinking for you. Even if you are smart and able to do pure math (which should give you a competitive advantage), it doesn't.
Interesting premise, lets see where he goes!
> I don't understand what is intellectually interesting about it.
Oh.
In other words, what's good for you isn't good for everyone. If you drop the selfish attitude you'll realize that your happiness matters to one person: You.
I'm not saying industry doesn't conceptualize unmet needs. I'm only saying that it's intellectually uninteresting.
