Well for example, we are producing far too much CO2 and plastic, and slowly killing our planet. Renewable energy has already been invented, but we continue to do these things because it is profitable. Unless we can invent replacements for existing CO2- and plastic-producing processes that are even more profitable, the status quo will continue.

I don't have an issue with trying to do said inventing, but when we put all our eggs into the deus ex machina invention basket, we are ignoring the sociological roots of the pollution, the fact that we could realistically stop now if only we had the political will, and instead opting for a hail mary.

I also find it frustrating that many of the people holding out for a tech fix are libertarians, and will actively oppose political solutions in favour of their faith in the free market.
