One of the technologies I look forward to is exoskeleton. Yes I know it will be used by the army. But the potential to improve elders' lives is huge.
I don’t think it’ll be a scenario like the starship troopers book, but having one available to a swat team or whatever, could be useful.
Still, I personally think the army would be one of the last applications, because that’s where you need the absolute lowest possible latency. Latency on a suit for an elderly person would be much more acceptable.
