I agree with you but I dread the day I need to change layout and train my brain and my muscle memory for another keyboard layout.

I'm past my 40s- I rather teach my kid to use Dvorak.

I’m kinda of the opposite. I think alt-layouts are only a marginal improvement (you can get most of the benefit with a small number of changes), but I think it’s a fun brain teaser.

I first learned Colemak-DH and I am currently trying RSTHD and I am upto 32 WPM in a few days.

In my 40ies.

The QMK and ZMK projects let you do this in firmware. Programmable boards are going to stick around long after we're gone. At least until Elon sells his brain-to-USB HID.
