I don't think we should forego many of the various amenities that we use energy for, but we definitely can reduce overall energy use without causing a humanitarian catastrophe.
Take transportation. Gas engines are somewhere in the neighborhood of 20-30% efficient; the rest gets wasted as heat. Modern electric vehicles use motors with efficiencies in the high 90's. With battery/charging losses maybe you're somewhere around 80% efficiency. It'd be nice if people drove less on average as well because traffic can be a problem, but even without that we could reduce the energy needs of transportation to less than half the energy we use now, just by being less wasteful. The transition to EVs is slow because EVs are still expensive and cars in general can have long lifespans, but we should be hitting an inflection point if we haven't already where new EVs are cheaper overall than new ICE vehicles, and in a decade or so that should be true in the used market as well.
There's similar gains to be made by using heat pumps instead of natural gas for heating.
We're going to need a lot more electricity production even in a world that uses less energy overall because a lot of the stuff that's fossil-fuel powered now will need to be transitioned to run on electricity. So, I'm in favor of vastly increasing our deployment of solar and wind farms, and nuclear.
The choice between faster innovation or do something to avert climate catastrophe is a false one. We can do one or the other or neither or both. I really hope we do something about the CO2 problem, though.
