Techno-capitalists expect innovation to save us, but it's what got us here

A third of food production on this planet done by smallholders, and the easiest way to make sure the other two-thirds doesn't get wasted is to change the distribution system (not with technology). It should not be used to make high-fructose corn syrup in the US. It should not be grown in Arizona to feed cattle in Saudi Arabia. The technology is a sticking plaster over our dumb world, and it is falling off
Then you realize most of our ancestors fled from both of these situations at the first opportunity.
Everything else is either trying to blame "the system" for ideological reasons ("capitalism is bad", "Westerners are bad"), or trying to cope by squeezing quality of life ("don't travel", "don't eat meat", etc).
If anything I'd say the main problem here is that the techno-capitalist are insincere about both and are using them as (half-literal) smoke screens to excuse using more fossil fuels in the immediate future.
But even in that insincere approach it's government action (or very rich philanthropy) that is required to do these things without direct market incentives.
