I think you're right. Why should we be surprised that an invention can do something that was previously thought impossible? Didn't some people from bygone years once balk at the possibility of a self-propelled vehicle? (read: automobile) Heck, there were probably cavemen who similarly doubted the wheel. Just about anything is possible once we conceive of it, and that's a fact.

PS But I will admit, those things look pretty dorky, and the guys standing around on them do too!

..just about anything is possible...

Yeah...but does it come with snow chains?
