What are LTs and GTs?
Still using Horsepower in the US? 22HP.. so that's 16 kW
I'm not familiar with Briggs motors, I reckon it's a big name in America.
I became a master mechanic, not by choice, but by owning a lot of old British cars under the Austin marque, and MG marque. x)
In the end I could do a complete tear down and rebuild of a motor in an afternoon, consuming a full box of Daz (wash powder) as hand cleaner.
That's down to the world being in a climate crisis, and an energy transition
to full electric -- Except for Trump's new empire, of course.

Getting back to Photoshop in Linux..
Those who are just starting out with Photoshop will need training -- Yes.
I never needed formal training in Photoshop, since I started using it in the 90s.
Each new version of Phoroshop had only minor changes, and a few new tools and functions, so bit by bit I adapted to all the versions up to the present.
I should add that anyone just starting out could just as easily use Affinity Photo, since there is no Photoshop UI habit to overcome.
Mind you, it means having to use Windows.
As for Illustrator..
Just started messing about with Inkscape -- I quite like the programme.
Never been thrilled with Illustrator to be honest, and Inkscape can also open files in .AI format. Exporting AI files means saving as .pdf, and renaming as .ai
in much the same way as M4V files can be renamed as MP4 files, without file conversion.
So Inkscape is quite enough for basic vector graphics.
