“Derangement syndrome” is anyone who doesn’t think Trump and Elon aren’t literally gods? You need to go watch videos of Trump from eight years ago and videos of him today. He’s not the same person. Sure, he’s not like a moron, but the his age is definitely not meaningless.

Yeah he seems tired
I don’t think they’re perfect, far from it. But “Trump is cognitively incapable” and “Elon spends all day on Twitter” are lazy, unserious criticisms that deserve a response in kind, sorry.
His age *could* become a problem, and I personally think there should be an age limit on presidential candidates, but right now he’s basically the exception that proves the rule.
Even Politico agree!
But, to get back on point, I disagree with your original suggestion that everyone should chill out. Everyone, irrespective of where they stand politically should be quite excited (in the physics sense) indeed. It’s not business as usual in DC. 
He seems as lucid as ever publicly, with a an actually discernible added measure of routine and experience.
I’d really strongly encourage you to watch side-by-side video from 8 years ago. Eg watch the two debates.
I watched him on Rogan, Theo Von and listened to his (mostly torturous) live X space with Elon - which was where Elon pitched him cold on Doge, as an aside. All live, unscripted, and extended performances. And just today i watched him speak impressively back in 2016.
I’m well aware, and I see nothing surprising or of particular concern for an almost 80 year old man who appears to be escaping dementia.
I would prefer to save the time, though I understand the relevance here. Do you mean that the so called weave, the tangents, have gotten more prominent?
Or do you really see another notable decline?
Sadly just a lot less overall clarity. Less coherent sentences making substantially less coherent points. People made fun of him eight years ago for this but mostly if you paid attention to politics and the goings-on you knew what he was referencing and he was making coherent arguments (whether you agreed or not). These days it’s much less follow-able.
I can see that, though he might have also just widened his scope a bit to personally less familiar topics during the second run, eg. BTC. The talking points during first run and term seemed pretty narrowly defined.
I didn’t say that Trump was “cognitively incapable”, you’re putting words in my mouth to argue a straw man. But, honestly go watch back to back videos of Trump. He’s capable, sure, but not what he was.
Ok, what did you mean by “Trump is literally ancient”? That he’s capable but less capable than before? Is that even a point worth making?
If so, sure…a somewhat diminished but more experienced Trump, and a 10x (at least) more capable and aligned cabinet is cool with me.
