>If we are worried about the environment shouldn't we be looking to economic models that don't rely on exponential growth and over-consumption.

I 100% agree with that and I think the main focus should be on sobriety, fast.

However, SOME tech will be needed, even in the context of a low-carbon sustainable society. How do we stay under the 2°C trajectory while maintaining a decent quality of life for everyone?

I'm no techno evangelist and I think there will be a LOT of bullshit to call out in climate tech, but some of it will be very welcome. For instance, having small, local, reliable and sustainable energy generation projects, or keeping our advances in medicine and agriculture while living with limited energy resources.

Definitely a lot to think about but I'd rather see brains working on that that developing the latest financial market algorithm for those sweets 0.00001 second automated transactions.
