That tracks. The defense primes have zero incentive to make things cheaper — their business model is cost-plus. A guy building something for 10k in his garage is an existential threat to programs billing 500k per unit. Of course they ignored him until the geopolitical situation made it impossible to keep ignoring.
I was talking about those that are meant for hospitals. Was peripherally involved with a fledgling startup that was developing something cheap. Hospitals straightaway said noway.
They would be desirable in places with poor advanced imaging penetration like Brazil. Usually only the largest city in a state has this sort of imaging.
We are heading to robotic wars where abilities and cost efficiency are the key factors. Like today drones in Ukraine war. Attack + defense + automation, + money + production
