The current model has weaknesses.
Ya think? It still sucks at scale and geometry, and especially doesn't do stairs well.
The people walking along the snowy Japanese sidewalk end up walking past a tiny kiosk full of tiny humans. The man's walking speed is normal while his companion looks sped up.
The guy reading a book in the clouds has the top-right corner of the pages blow upward from the bottom-left corner. Plus he's reading and he's black, so that's already unrealistic.
In Lagos, Nigeria, as it pans around, it regards the people and clothing rack next to him on the rooftop as being on the ground, so it's all tiny compared to him.
Possibly the worst offender is the Amalfi Coast video, where the people walking toward the stairs suddenly turn toward the rail and get sucked into a black hole as they touch it, while another set of stairs below narrows until it reaches a point and doesn't actually go anywhere, and two other stairways further down don't even make geometrical sense.
In the video with the cat, the lady's right arm is appropriately stretched next to her across the bed, but somehow the hand sticking out of the sheets is also a right hand, and when she starts to turn over, what is clearly moving as her left shoulder suddenly becomes a blanket.
There's a lady under the Chinese New Year dragon clearly holding up the pole used to make the dragon dance, but it isn't even connected to the dragon.
Horribly deformed human legs in the "robot on the sidewalk" clip.
What looks like the nose of a space shuttle suddenly rolls into frame on a roof in the clip of the old man thinking about the universe.
I'm amazed that with all the recent advancement, it's still making the same mistakes.
