I watched it, and it focuses on the intelligence, which is valid. The part that he glosses over, right at the beginning, is he says "solar powered" and then moves on to the intelligence.

There will be an intelligence explosion, but there is a tremendous leap from intelligence in a computer to a real world manufacturing system. Is the system going to build mining operations? smelting? etc. Going from sunlight to motion is a very intensive process with many different pitfalls and disconnects in between.

I want to see a computer build a design in Solidworks/Autocad/Freecad, and move that to a cnc machine and produce the final result, quality check it, and do it all within a confined power limit.

The reason humans have become so intelligent and conquered the world is because our power source, ie food - for the most part - grows passively on its own.

If the conjecture that it takes more energy to make a solar panel than it produces is within a factor of 2 to 4 of being true, then where do the robots get their energy from?

The important point to me is that electronics/mechanicals/robots, etc are extremely fragile compared to a human and carry all their energy in a single place. Humans store fat and can live off of the fat for up to 3 weeks or more and can be productive in that time.

Show me any machine that can run for 3 weeks on its own energy stores at a productive level, and I'll become scared.

When that rises up to kill you, let me know.
