Spinlaunch... Can it succeed?
Do you think they will ever get a payload to low Earth orbit?
Do you think they will ever achieve their claimed multiple launches per day?

Depends on your definition of success. Technically, probably. As a business, I don't know. Being limited to payloads that can tolerate high G is a bummer.
Probably. But at what cost?
If they can do one launch, they can do two. Second launch 23 hours after the first on the same day would satisfy the question.

Marco:
You could imagine it being used for bulk materials for a space station. The containment structure can be a heavy steel construction and then you just fill it with liquid oxygen or water or whatever you need up there.

I don't think satellites will like the G and tidal forces.

PS. the video makes a point about the shift in the centre of gravity the moment the rocket is released, you'd think the other arm would have a similar weight which gets launched and disintegrates into a pool, but maybe I'm underestimating the strength of the materials.

I agree with you.  Ultracentrifuges that get a little unbalanced are known to go through walls.  Of course, launching an identical projectile simultaneously in the opposite direction will have its own set of problems.

Doesn't have to be identical at all, just the same mass. Opening a water chamber on the opposite side could do it.
Alternately, a replacement mass could fall down the firing arm as the projectile is released. Or could even be part of the release mechanism when it arrives.
