If I have a a spaceship and you have a burning stick, you are technologically primitive. Being technologically primitive does not necessarily make you culturally primitive, for example...
If I use that spaceship to explode your technologically primitive culture to little bits because I can, it's highly likely that my culture is underdeveloped when it comes to finding non-violent solutions.
Technology is a facet of culture. Think about how useless a phone would be without the people and knowledge maintaining electrical grids, software, and data infrastructure.
Now consider that if the planet is a burnt out carcass that can't support life beyond bacteria that the project of technology maybe didn't serve us humans too well in the end.

Sure, but as far as I can tell, it doesn't seem to be.
If you don't feel the need to put a probability on your hypothetical scenario, you can doomsay anything, including what I would guess your preferred strategy to be: "Now consider that if the planet gets struck by a rogue cosmic body and shattered into an asteroid belt that the project of controlled deindustrialization and focus on conservation and social justice maybe didn't serve us humans too well in the end."
I don't see how what you're saying disagrees with the parent. In your first paragraph, no one is disagreeing that technology builds upon itself. In your second paragraph, the parent already concedes that if the technology is used badly, it'll...end badly, which is what you're saying too.
