I drive a giant motor home with headlights about five feet lower than my eye level.

Other cars’ reflectors work fine.

Sometimes it’s hard to read reflective signs above way over the highway, but retroreflective stuff at road level is definitely working

Yes, those count as technical skills and there are many, many people for whom it’s too big a hurdle.

picking out a decent micro PC that actually works is hard.

Getting a pc install (presumably windows) configured in a way that will display in the TV legibly from the couch is hard.

Requiring a keyboard and mouse to use your TV from the couch is weird and off-putting. Most people won’t want to and some people will have difficulty understanding what they’re supposed to do with these objects

The technical competence bar for getting a TV plugged in and working is just ridiculously, ridiculously low, and that’s for a reason

It does not — dumb people have the same access to the better drugs as smart people.

A eugenics-driven society where dumb people are left to die and smart people get extra health care likely would be effective at breeding children who are better at passing the “smart people” test, but I would not like to live in a society like that.

If you’re about to argue that having enough money to pay for health care correlates with intelligence… I would welcome some evidence. I used to think that was obvious but, having grown up and experienced the world some, the only thing I see that correlates with intelligence is depression.
