I think in the video there are some valid
and less valid issues. The Spike boards being specific and more failure prone in my view is an issue. With custom hardware ICs etc and no circuit board diagrams it will be hard to make them available if stern stop making them. And the price Stern charge for the boards sees excessive in my view with a warranty that's worse than than the half life of a good steak sandwich. I can imagine back in the day ops swapping boards in BW games to keep them running but if you have a specific GB failure then you are either carrying a complete set of spares ($$$$$$) or the machine sits in a valuable location powered off. Imagine ten years from now trying to get the board that drives the Rotisery in batman '66!
I also thinks he overlooks the ghosting issue which is clearly not resolved at all!
