What the left needs is a fucking spine.
You mean SolarPunk?
I would think any serious person worth their salt would take a luddite (by that I mean the values of the original bunch, not what the colloquialism has become) position and say that technology is as good as its implementation. If the technology makes it easier for people to do more in less time, thereby meaning that people can go do the fun stuff they enjoy doing, then absolutely. If, however, it’s implemented to drive down wages and therefore living standards, then it is not an advancement that we should seek to implement.
Saying the left is techno-pessimistic is, in my opinion, lazy.

Step 1: Connect all base commodities prices
Step 2: Find tech that makes one (most likely power) cost approximately nothing, causing all the other base commodities cost roughly nothing
Step 3: Though Makerspaces with tool loan libraries/DIY/AR goggles with open source AI/ETC… make it so that anyone with base resources can make anything they could ever want
Step 4: No more need to work for stuff.
We do, it’s even got its own community.

We’re perfectly optimistic about most technology. We can see how we can benefit from it, once most of the value it produces no longer ends in the owner class’es pocket.
