No.

It doesn’t really do anything I particularly need.

One needs to be compiled and the other is literally the de facto scripting language intended for exactly this purpose.
⁨Comment⁩ on ⁨I wrote a python script to backup my home directory⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:
A hilariously unnecessary Python script that could have easily been done in bash since it’s literally just a wrapper around rsync. 😅

When you’ve only got a Python-sized hammer in your toolbox, everything looks like a Python nail, I guess.
⁨Comment⁩ on ⁨What is best Lemmy App to use on iPhone?⁩ ⁨⁨4⁩ ⁨weeks⁩ ago⁩:
Voyager is the only open source one.

I would hope we would have learned enough from #enshittification by now that we would refuse to use others unless the devs open source their code.

Sometimes things that are repeated over and over again are actually true.

Just because you don’t understand how the world works doesn’t make this untrue.
⁨Comment⁩ on ⁨What Would a Fair and Community-Focused Monetization Model on the Fediverse Look Like?⁩ ⁨⁨1⁩ ⁨month⁩ ago⁩:
I wrote that.

Done engaging with you. Thanks for the talk.

I don’t have time to educate you but:
- civil asset forfeiture is a thing
- runaway inflation due to excessive money printing is a thing
- the work bank may not officially be a bank but what it is is a giant conglomerate of corporations that owns nations, takes part in coups, assasination, price fixing, and controls the dollar.
