The really clever part about this is that it's hard to tell whether it's mocking people trying to design new programming languages, or mocking people who criticise attempts to design new programming languages... or perhaps even both at the same time.
"People trying to improve things should be encouraged; even if they always fail"
No, people trying to improve things should be presented with (sane) "barriers to entry".
While there is no "right" way to improve things, there are tons of certified wrong, dead-end, been-here-done-that ways that should be avoided. Engineering is nothing if we don't learn from our collective mistakes, our history, and from proven theory. Else, you get the equivalent of those countless kooks who claim to have invented "cold fusion", "perpetual motion machines" but the "establishment doesn't believe them".
People trying to improve things is not by itself beneficial. Even if we restrict this to programming, we have fragmentation of effort, and you get like 200 frameworks for the same thing with marginal differentiation. If someone comes along with some radical idea, more power to them.
But we reserve the right to mock those coming up with YET ANOTHER tired cliche of a concept and/or implementation. They don't get free applause just for effort.
People that mock those people should be taken as amateur comedians, and should be on reddit (not here).
