Things is like publisher, illustrator, etc. can replace word. Open office is respectable. But all the google docs champions need to wake up.

Google docs is absolutely inferior in its power, formatting options, display performance, ability to write mathematical equations and diagrams directly into the document, etc.

Every time I had to produce a non-trivial report in google docs I grind my teeth and end up rendering these things elsewhere and insert them as png.

Additionally, google docs gives you no ownership over the software or the files I find it's commercial model unsettling.

What do you use for math document formatting and presentation? The publishing world I'm aware of is still running on Adobe.

LaTeX

For diagrams try draw.io

It's not like we are using modern products in most local companies I've worked for in the last decade. Everyone is still on 2008 and older office products. Hell I'm lucky we have AutoCAD LT 2014 at my current job. Its the most up to date piece of software in the whole office other than web browsers.
