So the OP's question was:

> Do you think that we'll relinquish control of our infrastructure including farming, energy, weapons etc?

To which I said yes. The reason is because AI will be more efficient than us at running it, which will lead market forces to make us relinquish control to AI, or be out-competed by those who already did.

If things went south at a power station, only very few people can respond, and in all likelihood they will no longer be there as they have not been needed for some time.

Practically speaking - you may want an AI to balance a national grid to optimise the use of variable renewable energy.

Such an AI will not be under human control, as it will have to act quickly.

So just like that we have lost control, and if the AI wants to bring down the grid there is nothing we can do about it.
