Short is relative, though... on average, they work for about 10 years, with some being longer. Most people's phones don't last that long :O Previous to smartphones, one of the biggest advances in mobility technology was the Trekker, and I don't think that lasted more than 5 years.
I've heard about the guide horses, but have not seen any (in Canada). I would love to talk to someone who has one, I can't imagine the logistics of getting around with a guide horse. Where would the horse be in a movie theatre?
I can see the potential for high tech vastly improve mobility (looking at Google's Tango tech), but I don't think it it close enough yet. But who knows, the technology may have a sudden advance in a few years
