Are you nitpicking that specific complaint? Or saying that Biden seems relatively okay?

Even the Democratic Party has given up on the far-fetched excuses. It’s time to surrender to the evidence. That example is just one out of dozens.

Laying out an argument (Biden mixing up names indicates he's senile) and having it disproven doesn't prove the case.

Biden is showing signs of decline, but the name-swapping thing was never (and still isn't) that. It's mental klutzery, nothing more. As the other person pointed out, it is /very/ common when two names are mentally-adjacent, to reach for the wrong one. My parents would call me by my brothers' names all the time, and I just did that with my own kids this morning.

Anyone who thinks that Biden got confused and thought he was in a press conference with Vladimir Putin (!!) is just spouting nonsense.

During the same event, he called his VP, Vice President Trump. Regardless of what you call it, it’s a bad sign similar to GW Bush’s constant gaffes.
