If someone comes up with a new port that had 10% more throughput than USB, do you think that will be enough to make it a viable competitor, or do you think it won't be worth the hassle of replacing your peripherals (cassettes) and computers (cassette players)?
Would you be willing to trust your child to the care of someone who is unwilling or incapable of finding work outside the jobs program?
For any useful job you can think of, ask yourself: What's stopping the unemployed from doing that job right now? They could already be making decent money driving or caring, so why aren't they?
I'm less worried about the current unemployed; that's a whole other can of worms. I'm more worried concerned about a supposed AI job-pocalypse where everyone (including me) can't find a job because AI robots can perform the role I currently perform, for cheaper, and tirelessly.
For the jobs that immediately come to mind, the reason there's no one working then is because I don't have the money to pay for them. I'd love to have a driver and a carer; There's a number of businesses I want to start but I don't have the money to hire people to do things so they limp along with the time and effort I'm able to give them after my main job.
> Imagine that our bitter ememies invented a superior logistics tool, known as the wheel. They also invented airplanes and the concept of blitzkrieg. Should we attribute their success to the wheel, and study how it was designed, since they clearly had a mighty army?
If you replace "wheel" with "jerrycan", then that's exactly what happened.
> Such was the appreciation of the cans in the war effort that President Franklin Roosevelt noted, "Without these cans it would have been impossible for our armies to cut their way across France at a lightning pace which exceeded the German Blitzkrieg of 1940."
The difference is during a regular meeting, the skin is uncut. The skin is a major protection against diseases and the body has a bunch of mechanisms at its regular openings (nose, ears, etc) to protect you.
When you cut through someones skin, you bypass one of the major first lines of defense. Therefor surgeons reduce the risks, for a similar reason why clean their tools before use.
