Robot muscles is way more interesting than leds. Just like our nervous system they respond to electrical pulses. It'd be cool if it could be integrated with human nervous system in the future to make awesomely realistic prosthetics. Titanium "bones" these "muscles" and some skin grafts.
Hopefully in the future, we will be able to repair/restore our muscles or "upgrade" to these muscles so we aren't slow and weak in our advanced age. The idea of potentially being stuck in a wheel chair due to old age just sounds terrible. We have several decades to figure this out, hopefully it is perfected by the time I'm extra old.
I feel like locking myself in my house for 40 years or so and having food and drink delivered to my door, then suddenly leaving and travelling straight to the city center to be overwhelmed by the future's wonders. Day by day nothing changes but looking back everything is different. I suppose I could just wait a few decades and jump right into the future like a caveman discovering a smartphone, staring wide-eyed at the confusing technologies that the common folk simply ignore and pass by, those same people staring at me like I'm a mental patient. Sounds like fun. Perhaps I'll pursue this preposterous ambition.
