Intelligence is not only embodied (it needs a body), it is also embedded in the environment (it needs the environment). If you want an intelligence in your computer, you need an environment in your computer first, as the substrate from which the intelligence will evolve. The more accurate the environment the better the intelligence that will be obtained. The universe is able to create intelligence and we are proof. Thus, if you want to create intelligence, you have to find a way of efficiently simulate our reality at the desired level of detail. Currently we don’t know such efficient algorithm, but one way could be finally harnessing Quantum Computing to hack the universe itself, cheat and be able to simulate our environment efficiently without even knowing the algorithm behind Quantum Physics.

Of course don't make the mistake that we need anything like a human body, or any singular object containing 'intelligence'. That's simply the way nature had to do it to connect a sensor platform to a brain. AI seems much more like it will be a hive mind and distributed system of data collection.

The silicon exists in the same environment that our brains do.

So your basically saying we need Dolores and Westworld
