TL;DR: what I got is that no they do not oppose technology per se, but they observe that how we use it is often very negative and destructive.

I can’t disagree with that part. We are a society full of angry unhappy people who like to break things. It’s deeply unhealthy.

Their view is that this grows out of our greed and imbalance, which demands eternal growth, which then when it runs into any limit reacts violently and aggressively.

This is where I stop entirely agreeing, though I don’t think it’s entirely wrong either. But I’d have to write a book for that.

In short I think there’s some truth here but there is also a lot more context and a lot more to it, and I’m not sure I come to exactly the same conclusions.
