The simple answer is, I choose to use Python because I am productive with it. I get a lot done compared to the other languages I have tried. Performance is almost never the limiting factor in my work, nor has it been for the vast majority of the work I've ever been witness to. When it is, it comes up in very particular circumstances, and can usually be fixed algorithmically. Indeed, that is the situation where I have used profilers.
The fact that the base language is an order of magnitude (or two!) slower has almost never mattered. If my work gets to the point where it does, and I have an excuse to go mess around with a rust extension or some cool optimized library, things are going very well.
I've been professional developer for over 20 years now, and I've read this forum obsessively for much of that time. I've seen people write things like, "Most engineers would kill for a 5% speedup" and I think, on what planet? Most engineers have much larger problems that cannot be so easily quantified. Come to think of it, I think that there is an allure to performance optimization due to the fact that it can be so easily quantified.
