Well, if I were in the industry and designing/producing said hands, the mechanism and superstructure would be sealed. Even if only for durability's sake. After all, I bet there are soldiers with bionic replacements. What if the coverings are melted/torn/shot off [etc.] and they have to treck hundreds of miles through the desert to get to the nearest base to be sent home?
I used to work with a company that put together computers for military use. The process consisted of dismantling ordinary home computers, scrapping the original, less robust cases, connectors, mountings and cables, then replacing them with more robust components, e.g., metal cases, heavy-duty cables etc. Probably cost a mint, but that's what the military pays for -
military-grade equipment.
My point is - do
we get military-grade stuff? - no, we get cheaper and (often) nastier. Military-grade is better quality for a
reason.
Can't have their bionics giving out because they weren't dust proofed. It seems like a poor marketing strategy to me. "Hey, our robo-hands work just like real ones, but a firm handshake will crush them, and we force you to wear coverings because they weren't finished enough to be resistant to particle ingress! "
Well, that's the world of marketing as it actually exists!
For instance, look at cars - you can get everything from a Bugatti or Maserati down to a Pinto or a Yugo!
I can get a Samsung or iPad tablet - or I can buy the
thing that I actually did buy... (You get what you pay for
)
Business will
sell what people will
buy - and if we can't afford a better machine, we might be buying something more dodgy.
I suspect Clinton's family isn't exactly rich - maybe his hand is simply the budget model? ("Budget" often being a euphemism for "cutting corners"
)
