I think it depends on what the thing is. I use LaTeX for occasional documentation, a better version would save me a maximum of 5 minutes a year. I probably won't be an early Typst adopter.

But, I spend loads of time for example, working with dataframes in Python. I got into Polars fairly early because improvements in that space can massively affect my productivity.

If you're routinely using LaTeX to write papers, the time spent learning something new isn't comparably large.

If a better Latex only saves you 5 minutes per year, then that means, that you are either a latex god, who types 200wpm in special characters and talks latex fluently, or, that you don't actually write much documentation per year, or, that someone else has invested significant time to create all the document layout, macros, environments, etc. so that you only need to type the text.

My point is, that creating a proper latex document, specific to one's use case can consume many hours of time.

I don't know. By then aren't you quite comfortable with LaTeX?

It may be Stockholm syndrome and sunk costs speaking, but I'm using LaTeX all the time: I quite like it and I don't feel any need for something else to replace it...
