As far as baseball (or other sports) the players make many mistakes every game. Should we replace them with robots? Again, fairness is not a measuring stick it is a mindset. We know players cheat so the fairness thing doesn’t wash with me.
I think maybe consistency is a better word for it. I want consistent officiating in any sport. It's why sports where time matters are timed by automation now, not people with stopwatches. I know players make mistakes and that's part of the game. The other side capitalizes on those mistakes. If we played baseball with robots every game would probably be a perfect game with no hits, no runs, no walks. Who would want to watch this?
We absolutely need to work. We were hunters and gatherers before this modern age. We gain harmony when we are working by seeing the fruits of our labor. Many people, after retirement, return to the workforce because they miss the positive results of what it brings. It’s not dehumanizing it’s humanizing, it’s what we are.
We need to do
something. I agree with that. It doesn't need to be a full-time job. My late father seemed bored during retirement. He spent a lot of time watching TV or doing "hobbies" which weren't particularly engaging, mostly just collecting stuff. I could make the argument that many of the people bored during retirement are this way because decades of doing a mindless job on a set schedule destroyed their initiative. Indeed, I saw that happening to me after working only a few years. I said to myself I have to get away from this. I did by starting my own home business where I work my own schedule and probably never averaged over 15-20 hours a week. That's an average, mind you. I've had busy weeks where I put in 70 hours but also had weeks or even months completely off. I was never bored.
I think my father's job killed all his initiative over the decades. He used to do a lot of fun, creative stuff when I was a kid. That got to be less and less as he got older. I even offered to get him a computer but he had no interest in learning anything new. Really sad.
Now, there are extremely dangerous jobs, like checking to see if a bomb is live or needs to be deactivated, that I am all for robots to do. Go for it.
Collecting garbage is one of the statistically most dangerous jobs believe it or not. It also kills your back. Delivering food is another very dangerous job, especially in NYC. Long-distance trucking is dangerous also, more so to the people in cars who are at the mercy of tired, overworked truck drivers in charge of an 80,000 pound semi.
It's not just dangerous jobs which need to be replaced but also boring ones.
Automation of the likes you are hoping for will destroy humanity. Be careful what you wish for.
There I have to disagree. I think it'll usher in a new golden age of humanity where people can choose their own paths, free of the burden of needing to do something just to pay living expenses. I see what people come up with watching you-tube. All sorts of creative pursuits. Many of these people are only able to do this because they're free of needing to work. I think we'll become a society of artisans when automation takes over. And don't think there won't be a demand for human-produced goods even once the machines can make virtually everything we need. The slight imperfections of human-made furniture, for example, will have appeal to some over uniform stuff made by machine.
And of course we'll start exploring the universe. That will keep us occupied literally forever.
It's definitely a concentric circle of torment.
