I think we still have many high-IQ people on the web. Its just they are not making tiktoks. However, they are harder to find since the pool got bigger.

The ease of use introduced the average individuals to the web and online gaming. When I was younger and online gaming was gaining traction my "clan" hosted servers. This is how I started dipping my toes into programming and server configuration. Literally, everyone that was in the clan was quite intelligent. We had debates and discussions on IRC, forums and teamspeak.

Now, gaming and the web is just trash full of brain rotted individuals. Communities have been destroyed by lack of self hosted or self owned servers. Forums have been destroyed by discord. Games are being destroyed by microtransactions.
