Design: Modern design sucks. Everything after 1990, especially after 2000 is completely shit. I truly mean all design. Industrial Design to Architecture to the garbage you see in the browsers today. We threw away physical controls, can't even find them. Alps catalogue is dwindling and toggle switches are no more. Go explore how things used to be done, look up advertisements from 1970's. Also, the Big Tech design monoculture is shit. Everyone suddently in 2020 decided to add rounded corners. It happened almost overnight like a meme spreading through the design circles.
Globalisation: Imagine if you were to travel to Japan in the year 1890. Everyone wore kimonos. It was a prestine, isolated and incredibly rich culture. Same with France or US or any nation. It is fun to explore how US and USSR had invented stuff during the cold war. Russia had their own mechanical watches to titanium alloys. When large groups (millions of people) are isolated, they can create some amazing stuff on their own. Connecting the world with wires was a bad idea. It destroyed cultures into a giant globalised culture. I wish Globalisation didn't happen and the internet was never invented except for highly controlled and regulated uses.
Masks: Facial expressions are key to communication and we've just defaced our selves in public settings, possibly forever. This is not good. Humans evolved to look at faces and see expressions.
Edit: Interesting to see downvotes in a thread about outrageous ideas. It only confirms it!
