Spaceship from the movie A Space Odyssey 2021 by Stanley Kubrick

The software industry is relatively young.

Writing the code is much easier than writing an essay in natural language. The programming language is primitive. Several dozen word constructions of which only a small set of what is available is used. This is why programmers are so eager to
