Re: Five technologies you shouldn't bother looking out for in 2016
"Anyone non-IT professional who uses Linux desktop does not really need any desktop at all"
What an extraordinary claim. Almost all the people I know personally who use Linux desktops are NOT IT professionals but are scientists & academics. The reasons are complex but the simplest is that a lot of scientific software was written for UNIX and has been ported to Linux. The subsequent ports have been improved, extended and adapted to newer hardware. The other major reason is the availability of compilers/interpreters for a range of languages as a lot of scientific software is written/adapted by scientists for peer consumption.
If you doubt the existence of commercial software of a highly complex nature for Linux can I suggest :
It's even (mostly) available for Windows these days
