The older videos explicitly tested early alpha and beta versions. Meanwhile it is already released as official version with their distribution. Off course there might be quirks (like KDE has in example), but its ready for productive use.

Probably depends on the species. You did not specify human, so we have to assume its alien.

You probably meant “DE” instead “IDE” (i was confused first, but think its a typo). You should look in YouTube videos to get an idea of what it is and how it works. I would say, its something GNOME 3 inspired by its look and design, but with functionality and customization inspired by KDE. Some parts might be still under cooked, as it is still early. The question is, why do you want change from KDE? This information would be crucial to give a recommendation. And only you can answer it. Maybe try it out in a virtual machine before committing installation on your main system.

I don’t know…

Totally understandable. It took me years and years to get used to and to remember how it even functions (was it 2 or 3 angled brackets?). Just to be clear, this was not a critique or attack (as you defended your way of doing :D), I just wanted to share another possibility.

Just a little note, that you can use the Bash “<<< heredoc” sed 's/l/x/g' <<< 'hello' to read stdin, instead using echo for this job. The reason is, this is more pure and direct without any alteration compared to processing with echo.

How is this Linux related?
