LaTeX is great but it’s not an office suite.

Reasoning about memory use for example is difficult with FP.

Using pure functions is a good idea for non FP languages as well.

Functional programmers still pretending side effects snd reals world applications don’t exist.

LaTeX is great for documents, mediocre for slides, questionable for spreadsheets, useless for mail and calendar.

Matrix/Element has shitty usability and reliability compared to Discord.

For lots of communities, they could use modern forum software like Discourse with better results.
