23' span sliding deck over pool??
(OP)
Do you guys think it's remotely possible to have a 23x23 box that rolls off a pool? It wouldn't need to support additional weight and would only serve as a cover. Youtube video of it

It's a Wonderful Life!
Please remember: we're not all guys!

Assume a 25ft simple span and W-section beams spaced at 6' O.C.
1.6*100psf*6ft*(25ft)^2 / 8 = 75 kip-ft
Quick and dirty I think a W12x16 would work with lateral braces every 3ft.
It does seem like the design from the video could pop off the track very easily.

I use 40psf for everything but commercial.
The biggest cost was likely not the beams or decking but getting a reliable trolley system to work.

I would argue no. Less than 24" drop for starters. Wouldn't you then require guardrails continuously around all pools?

40psf is definitely for residential decks.
If the deck is NOT classified as residential, then the non-consensus opinion in our office is that the deck is an 'assembly area' and thus the 100psf loading is appropriate.
I say non-consensus because some engineers in our office do a strict 100psf live load, and others are okay with reducing the loading if its a low occupancy non-residential deck.
