Greetings, I hope you are well,
The way I feel about it is that most of the problems our world has today are temporary. Future generations will have to face their own problems, and they may even look back at our current issues with a healthy dose of laughter. But the fact is that we do have problems in our world. The cause-and-effect of having a problem is that we either solve the problem or we suffer from it.
I appreciate your point of view, it's refreshing. But personally I would prefer to spend the effort on the world, I think it's worth it. Solving a problem in the world is not impossible, any one of us can do it, we don't even need to be elected. The downside of making the world a better place is that good times can make some people go bad, it's a balance that's built into the human race, and it's one of the reasons why I believe that people in the future will have their own problems no matter what we do. But that's a problem for the future to solve.
About the issue of our antibiotic medicines losing the arms-race against the biological evolution of germs, I'm sorry but it's inevitable, although it's not binary; it won't happen all at once and we won't all die, but it will make Covid-19 look like a dream. The truth is that viruses and bacteria evolve very quickly and we won't always be able to keep up with them. What makes it worse is that antibiotics (even the antibacterial soaps) don't always kill all the germs, which leaves only the strongest germs to repopulate without competition from the weaker germs.
Scientists have known about that problem for decades, and they still don't know what to do about it. But all it will take to solve it is one viable idea. Nobody has to fight anyone over it, there won't be any high-speed car chases, there's no person or government standing in the way of a solution to that problem. Al it will take is someone putting the effort into thinking of a solution. But then what?
Let's say or example that you figured out a way to solve it, for the sake of argument let's say the solution is to stop using most antibiotics unless they're required to save the patients life and instead treat most infections with something like colloidal silver while boosting the immune system with certain medications and medical procedures like blood-oxygenation. So, now there's an idea for a solution, but then what? You should tell someone, shouldn't you? What's the point of having an idea that could change the world or save lives and just keeping it to yourself? To me that seems like a tragic waste.
I respect that you may prefer to look at the act of problem-solving from a spiritual perspective that you deal with internally, there's a lot that can be accomplished that way. But some problems are external by nature. I believe the world may require both (an internal and external approach) from us.
