It's like any celebrity, they exist as a meme in the eyes of 99% of people. Not as a real person.

And it's been known a while that the deep state (the corporate/lobbying/regulatory capture groups) basically runs things and the president is just a PR figure. That's been increasingly true for decades. Biden just makes it almost impossible to deny, it's like "Weekend at Bernies".

They just manage him and then give him the right pills before any press conferences so he's as lucid as possible. 90% of a president's job is PR meetings as a figurehead, not doing legislation or understanding the issues. I think that should be obvious to everyone at this point in history, the last 4 presidents or so made that pretty clear.
