According to convention The Big Bang produced machines first, then biological entities, and finally humanity.

Some scientists are saying humans will evolve into sentient robots, leaving the biological behind.

Wouldn't it violate Dollo's Law to evolve back into machines?

The giant machines of the early stellar universe were very simple - just big hammers and stuff, on pulleys - so the new ones will be something different.

And the tapeworms have asked me to remind you that the Big Bang did not stop with humanity - more advanced creatures have come along since.

I can’t see how we could “evolve” into cyborgs/robots in a purely biological sense. In other words, genes and biochemistry can’t make metal and synthetic structures for our bodies. This will be a purely man-made and man-directed event. Sure, once we’re on the way to becoming robots natural selection might make such moves advantageous, but inserting metal/synthetic parts into a body will still be at the discretion of human beings. Thus, I can’t see how laws that describe natural phenomena, like Dollo’s Law or others, can be applied.

(I’m not sure I’ve made myself very clear. )
