- speeds matters of that level matters only for a limited number of use cases. Most programming use cases are fine with python speed. They were fine, in fact, with it 20 years ago, before we got that hardware speed.
- people are starting to complain about speed in python only because of all the data science going up. Suddenly here speed matters. Before, you had to get to google level of infra to find use cases where python was too slow.
- dev are expensive. Hardware is cheap. If you have a slow website, paying $200 dollar more on your server is not a big deal. But taking 3 more month dev that features with your $300k pro is another thing entirely.
I’ve never had an issue with a Python performance, not in twenty years. Possibly because of using it for what it’s good at? Every year it gets faster as well. I did have an issue with the performance of Java twenty years ago, but that was a long time ago of course. Computers at an order of magnitude faster now and java startup improved.
Python is often 1-2 orders of magnitude slower than java. That really is a lot yet Python and Java are about comparable in adoption.
