When I am King...
All knees will be replaced by more functional joints.
I had knee surgery a couple of weeks ago, basically because I'm getting old. They poked around in there, shaved some, scraped some, put me back together. Now my knees feel grate; they grate every step I take. They sound like a couple of maracas; like my knees are some kind of Latin joint.
The knee has to be the dumbest joint ever invented. I think it probably worked fine back when people lived to, say, 22. But we're taking these things way past their warranty expiration, and the manufacturer is no longer in business. Can you imagine the class action suit for this screwup?
I can't believe that we evolved this joint; it just doesn't make sense. Evolution is supposed to improve upon things, make them better through the generations. Like our ability to detect prey in the area. Or coffee.
So how did knees get past the Quality Assurance Committee of the Evolution Task Force? Do you think anyone actually thought about them? “Hmm, here's one - Requirement: Needs to hold up to 100-250 pounds comfortably for up to 100 years. Proposal: bone sliding over bone. Thin layer of deteriorating cartilage. Works for me. Now where'd I put that other six pack?”
Instead, I think knees were imposed, maybe as a punishment, or as a practical joke. “Think thou can Flee my Wrath, eh? Well try it with these! Ha ha HA ha ha ha. HA!”. (Gods generally have poor senses of humor, and there is no hope of improving because noone ever tells them their jokes suck).
Or maybe knees were just a temporary measure, like the awful rental you get when your car is in the shop; it gets you to work, but you can't wait to get back to a real car. But the shop closed down, we never got our real joints back, and we're making do on rentals that have gone way beyond their mileage limit.
Help is on the way. Humanity didn't evolve better joints, but we did evolve surgery. In my kingdom, we will mandate surgeries that will do whole-knee replacements, but not with other knee joints (what a bad joke that is; it's like returning a meal because it has a cockroach in it and having the chef transfer the same roach to a new plate of food for you). Instead, we will replace knees with something else entirely.
We do not yet know what the solution will be like; we will create research foundations to find the answer. One possibility being weighed is removing our legs entirely and fastening our bodies in place, but working out a system to move everything else to us. It would be far easier on our bodies and much more convenient. Exercise will be limited, but we expect the remote control to be so complex that simply lifting and operating it should suffice.
