(17,469 posts)and they are not trivial. Simply coming up with a power source to run the robot for a reasonable length of time is decades off. What good is a robot that can work for 15 minute, then has to recharge for 45? Or if you give it enough battery capacity to work a significant amount of time, you triple it's weight? Simulating human intelligence is about massive parallel computing, which consumes huge amounts of electricity, and then doubling that number to add a cooling system to shed the heat, which also adds more weight. Humans manage the same feat in a package weighing in at under 200 pounds and consuming a few kilowatt hours of power daily.
The same people who have been telling us AI is very close, have been telling us that fusion reactors, flying cars, and lightweight, energy dense batteries are just 5-10 years away, have been telling us that for decades. People throw out words like "quantum computing", "neural networks", etc like sci-fi writers throw out "warp drive" and Heisenberg Compensators. They sound impressive, but in reality they either don't exist, or don't really work as simply as most people think they do.
The human brain is the end product of millions of years of evolution. It is a marvel of chemical/electrical/bio-engineering. We are not going to invent its replacement in a few decades.
