My wild guess: It’s the increasing atmospheric concentration of carbon dioxide.
It’s a well-known effect that increasing CO2 levels makes people dumber when it goes above 1000 ppm. When atmospheric CO2 goes from 200 ppm (last century) to 400 ppm (the current state) indoor CO2 levels can reach that 1000 ppm state that much quicker.
So yeah: Yet another reason to stop using fossil fuels.

Maybe it’s the micro plastics in our brains. So many fun things to think about.
also a good reason to open the windows or even better, go outside.
