Kind of feels like the recent couple of years in the US. Only we don't just get news twice a day, we're constantly inundated with it. The same advice is given now, only it includes not just avoiding the news but also social media - in my experience it's pretty essential advice.
So a lot of what Kurt Gödel did was follow a fairly inevitable progression before anyone else. And it is one of those ironies the result, that the-provable and the truth are far apart, did not please such a brilliant idealist.
Edit: From wikipedia: "Mathematical logic emerged in the mid-19th century as a subfield of mathematics, reflecting the confluence of two traditions: formal philosophical logic and mathematics (Ferreirós 2001, p. 443). "Mathematical logic, also called 'logistic', 'symbolic logic', the 'algebra of logic', and, more recently, simply 'formal logic', is the set of logical theories elaborated in the course of the last [nineteenth] century with the aid of an artificial notation and a rigorously deductive method."[3] Before this emergence, logic was studied with rhetoric, with calculationes,[4] through the syllogism, and with philosophy. "
I read a tweet recently that seemed to summarize Kant as having done something similar for knowledge, and I immediately thought of Godel's incompleteness theorem. Obviously I don't claim to fully understand full threads of their works, but found the connection interesting (and Kant finally accessible perhaps)

> Kurt Gödel, only a year beyond his PhD, announced a result which would forever change the foundations of mathematics. He formalized the liar paradox, "This statement is false" to prove roughly that for any effectively axiomatized consistent extension T of number theory (Peano arithmetic) there is a sentence σ which asserts its own unprovability in T. John von Neumann, who was in the audience immediately understood the importance of Gödel's incompleteness theorem. [...]
> In the next few weeks von Neumann realized that by arithmetizing the proof of Gödel's first theorem, one could prove an even better one, that no such formal system T could prove its own consistency. A few weeks later he brought his proof to Gödel, who thanked him and informed him politely that he had already submitted the second incompleteness theorem for publication.
was for Russell's Principia Mathematica, which is much
stronger than a first-order theory of the natural numbers.
Also, Gödel's incompleteness result was not for the liar paradox.
Instead, it was for the proposition I'mUnprovable, which
[Gödel 1931] claimed to have constructed. However,
[Wittgenstein 1937-1944] showed that I'mUnprovable leads to
inconsistency in the foundations of mathematics. Fortunately,
I'mUnprovable cannot be constructed in foundations because
the attempted construction violates order on propositions.
Furthermore, Gödel did not have a proof of the second
incompleteness result at the time he wrote to von Neumann [von Plato 2018].
von Neumann never realized the deception by Gödel because it
was discovered after both had died.
Wittgenstein [1937-1944] had shown that Gödel failed to prove
incompleteness of the foundations of mathematics. Gödel was
aware of this failure but tried to bluff past it claiming that
his incompleteness result was not for the foundations of mathematics.
Contrary to [Gödel 1931], he claimed decades later
that his result was for a limited first-order theory of the
natural numbers [Wang 1987].
However, the failure may have secretly weighed on his mind.

I remember reading some short bios that (with a wink and nod) mentioned Godel had a relationship with a cabaret dancer. I remember absolutely detesting it.
Making a life with a genius, obsessive compulsive individual doesn’t seem very easy to say the least.
Nevermind the importance of the individual to society, and the implied responsibility that came with it.
For example, Cantor, Boltzmann, and Turing ended similarly :-(
