I use these moments to discuss that topic and dive a little bit deeper into it. If a child is interested enough to share something, then perhaps the sharing can go both ways. As long as we stay within the same topic, the child is usually willing to learn as well.
That’s just natural selection doing its thing. I don’t think the anti-vaxxer philosophy will completely disappear, but the number of people believing in it will be cut down by various diseases such as covid. Those who survive, will probably be damaged by said diseases, so who knows how well they’ll be able to articulate their thoughts after that.
I hope that one day I’ll have a super powerful completer capable of running a full VR simulation of the entire world and a million years history. One day, I would visit that simulation, meet some of the NPCs in it, and tell them that they don’t really exist just to see what would happen.
This is the way I would want to see it happen. If pollution tax is high enough, it will incentivize companies to act more reasonably. Hopefully coal power plants will shut down permanently while blast furnaces will be modified to meet the new requirements. Processing all of that CO2 won’t be cheap, but steel production has to continue so the company doesn’t really have that many options. The government could also support the transition so that production won’t disappear into other countries.
If you’re going to capture any of it, you should build your capture factory right next to the source such as a blast furnace. In normal air the concentration is so low that you end up playing that game in hard mode.
