At that time, this new Python language was a curiosity. It was nice that you could easily replace dozens of C code with one line of Python but everybody was aware it's too slow. However, this window shifted with time. The perceptions of "fast" and "slow" changed for various reasons such as network delays so Python became acceptable in many areas it would be dismissed otherwise. To the point it became the no. 1 language now.
But we are not in the 2000s anymore. We do have powerful, batteries-included languages that are faster than Python. So I expect with time, large parts will be rewritten. However, the area related to scientific computing will stay with Python, just like Fortran programs continue to be used today.

Not for me. Printing HTTPie's version takes longer than to finish a real http request with xh. I suspect it's because I'm testing it on a relatively old server where the differences are even more pronounced.

I'm using HTTPie 3.2.1 because Arch doesn't have the latest version available but based on the release notes that shouldn't make a difference.
