First VR, next human to power conversion.... let's call it biofusion.

then a nuclear winter, which probably be China Vs America.

and suddenly the machines have won.

I'd say no. Especially the whole idea of human batteries. They are very inefficient compared to other energy sources. And wasting that miniscule energy on brain activity would be a huge waste in the first place. Leaving people conscious would be defeating the whole purpose of extracting energy.

Additionally, even if the brains would still be working, using them to simulate the usual human rat-race instead of some more purposeful computing is still utterly pointless and would waste energy.

If it can, it has been, but we'll never know

Yes why not👽

We already live in one, our consciousness is exiled here to serve sentence in prison.

I don't think you want to find out what is real

Yeah, a company called meta is building it

Kinda depends on what your definition is. I mean what aspects. Add others pointed out the energy conversion thingy is a bit weird. Why bother with huge amount of computing to keep your batteries happy.
Other things are not such crazy ideas. If humanity survives long enough
