You are so very spot on with this. All of it. Literally nothing is better in the UI world in the past 20 years. Zero. We already had multitouch scrolling on laptops back then.

I don’t think it’s a stretch to say that most of the problem can be traced back to the transition to Mobile first design. The motivations were arguably pretty innocent in general. If there were no downsides, it’s nice that there isn’t a separate code base and an entirely separate set of capabilities for desktop and little 5-inch phone screens. However, the way that we have achieved that - nearly across the board - is by lobotomizing the experience everywhere.

And because of fashion (those artists who control the UX can’t resist it), even in places where that doesn’t even make any sense because there is no mobile version (say, B2B SaaS products that only get used on a desktop), they still feel the need to cosplay as a mobile app by using all the same stupid design elements (the ••• and “hamburger” menus, the giant grids of “tiles” that should have been a table, etc.
