Oh, and talk to me when you do programming, graphic design, web page creation, CAD design - electronics or mechanical, your choice - on a tiny screen with no keyboard nor mouse.
Lol - lets not pretend that I don't read ~100 documents a week, write and review proposals, drafts and P&IDs, submit permits, write reports, print and send (real!) letters, etc. I also edit dozens of photos weekly (sometimes hundreds!) and I use my nicely laid out desk with desktop.
The benefits of doing certain tasks on a desktop are certainly known to me. That's not what you're arguing though. You conflate "I don't have a need for this usability" or somewhat differently "I don't prefer that interface" with "that usability is stupid/silly/some-other-boomer-reference" - which isn't how that works
