But the lump of labour fallacy is wrong - in the end automation makes us all wealthier as goods become cheaper, and people can do more productive work (and be better educated for it too).
It really is. Degrowth is destitution and death - just look at Germany.
We need to decouple electricity production from environmental damage - build renewable power and nuclear power station en masse and invest heavily in nuclear fusion.
Wtf is a "professional communicator"? How do you think you get there?
They just needed someone who wasn't really weird, and had a proper job. Look at Mick Lynch's interviews in the UK for example - he did great work for the union.
The issue is the physics. 60Hz doesn't give you much time to do everything that needs to be calculated in the interval. All the objects can interact with one another so it's not easily independent and parallelisable.
There's still optimisations that can be made - disable physics and have only certain actions enable them for nearby objects, smaller physics range, fewer physics-enabled objects, etc. - but those all have drawbacks for the gameplay and realism too.
Just use Steam.
