This question was inspired by my hatred of Temporal Anti-Aliasing which, in many games nowadays, is poorly used as a performance bandaid. On lower resolutions it will smudge and blur the image and certain bad cases of TAA will cause visible ghosting.
Yet in spite of all this, certain games won’t let you turn it off or have hair/fur/foliage look like dogshit without it so sometimes I still use it.
I don’t even know if YouTube will be around in 30 years, let alone not have competitors.
All gigantic businesses think they’re too big and entrenched and used every day to fail, until they do. Just look at Yahoo! as one example from recent memory.
So, we’ll see, I suppose!
In the end I am just a dummy on the internet speculating. For all I know climate change will be coming down from the top rope and take Google with it.
