Personally I think it looks both incredibly ugly and also really non ergonomic.
I can’t see it being comfortable to hold and type on at all.
I predict the form factor will be gone within two years.
I have a Samsung Z Fold 7. The stock keyboard is split so it's a bit more comfortable to type on with my thumbs. Granted, this phone is the square form factor and not the wide version but I think the concept stays.
My iPad from 2018 still has a full width keyboard so I have to hunt and peck which is annoying. I would hope that apple designs this better for the iPhone duo.
Given that it's basically an iPad at that size, and those have been around for 16 years, I wouldn't be so sure about that.

I predict you will be wrong.
I have a few qualms with this phone:
For an Android user, you can already build such a system yourself quite trivially by getting two phones, attaching them with a small hinge or case, and using an app to synchronise content between the displays. From a laptop or tablet, the same applications and files could be accessed through existing cloud services
