It never states that they had these in their birth years. Just that they had them. Might have been in the 2020s with the Koenigsegg Jesko Absolut, which is the fastest car and was built in their lifetime. And coincidentally, currently the fastest in my lifetime as well
If smart people love libreoffice, then I must be dumb. Working with it always seems weird and I never like it.
Fortunately, I can use LaTeX for work; it is far from without issues but while being arcane sometimes (especially when tables are involved), it never really upsets me and the result looks very good. I can say neither for libreoffice or MS office. But at least the former doesn’t charge for the experience.
I hope typst gains more traction; it seems really intuitive compared to TeX and you don’t necessarily need a macro package. And while it doesn’t produce the quality of TeX-based systems yet, it is already good. Then again, Knuth’s goal first and foremost goal was quality (and it shows); the system just had to be usable by him.
