Would it be great to create a universal programming language?

Question

Programming

Or will they be able to realize their potential only individually?

Answer 1

It's impossible.
Languages ​​have their own properties, which are pluses and minuses, and these properties become pluses or minuses only in certain areas of application.
Let's take dynamic typing. For rapid prototyping when creating startups, this is a plus. For enterprise projects minus.
Take the bytecode. For business applications and startups, this is a plus. For system software or graphics engines - minus.

Answer 2

It already exists - it's C++.
