Half of humanity is not very smart. Once you've sold computers and software to everyone who is smart, you have to sell to the not smart half. And that not smart half isn't going to like or even be able to use complex software. Since there are far more people out there simply consuming things and few people creating things, the bias is going to be for the simpletons.

Software and technology went from being a productivity tool to an ad delivery vehicle (or delivery vehicle for whatever bullshit is en-vogue like media subscriptions, AI, etc - that ultimately sooner or later comes back to ads).

Turns out you don't actually need much UX or design when the product's productivity capabilities no longer affect your bottom line.

My question is what those people think will happen when the transition completes and everything fully became an ad delivery machine with no productivity features? Ads only work as long as people have disposable income to spend on the advertised products/media, and they won't be having any money if you break the productivity tools they used to make said money. Ads can't work if the entire economy becomes ads.
