I agree with your comment.

However, cough cough Akshually…

While genocidal they lost the title of MOST genocidal dictatorship. CPSU even at moderate estimates is much higher than Nazis.

Unless “most” means people/year performance to you?

I’ve seen a video of US Navy using an Xbox controller (arguably for experimental weapon iirc but still). If it just works why overengineer it? I would be more concerned about that hull (scuttlebutt says it was just carbon over titanium frame, not titanium hull overlayed with carbon). However I guess we will have to wait until they find the boat to know the reason for failure.
