Think about some examples.
MongoDB is nothing but the object databases of the 80's, rebranded. It's main selling point is "you don't need to learn SQL". Object databases failed and people at the time were willing to learn something new (SQL). Nowadays, who will do that?
Go's entire selling point is "faster than python, no need to learn anything new". In terms of language features it's again living in the 80's - Java got generics in 2004 and Java was way behind the times. In terms of speed it's worse than Java and Rust, maybe comparable to Haskell.
And NodeJS is nothing but "write server code, no need to learn a new language". Isomorphism simply didn't work. People think Node is fast because it can do async, but Java has been able to do threaded async for 15 years.
I wonder how much the industry could advance if we could simply persuade every developer to learn Java Postgres.
