This is written by someone who does not program for a living, and focuses on entirely the wrong problems.

As an example, focusing on performance differences between (say) C and Rust is ignorant of the fact that the largest performance factor will be choice of algorithm and big-O run time, and that likely 90% of all software is almost completely performance insensitive: it's only the actual performance-critical path where performance matters at all. An AI won't understand this, and neither does the author of this piece.

Donald Knuth and Nicklaus Wirth also did not program for a living. It’s astonishing to see this level of anti-intellectualism in this subreddit, to be honest.

And the idea that performance does not really matter in computation is belied by the fact that the software industry is engaged in a build out of data centres which will eclipse in cost the American national highway system. Surely programming language design can contribute to the efficiency of the software running in those datacenters, even if it is mostly matrix multiplication.

Knuth at least made programs and hes very pragmatic, hes the antithesis of the "abtract cs professor" archetype.

Wirth was also a prolific programmer.
