It is undoubtedly true in an economic sense — if you can build a true AI, pair it with agile robotics, you’ll have (effectively) infinite services and manufacturing capacity at a cost of the unit’s depreciation and energy — anything which doesn’t rely upon absolutely rare commodities (not just ones that are expensive now because of production costs) will start out cheap and quickly become essentially free at the scale of individual consumption.
If one company, or country, or an oligopoly of them, controls the technology, anyone outside the sphere of control has instantly lost almost all the value of their productive capacity (be it labor or industry) and most (if not necessarily almost all) of their other assets, too ... not good.
Machines don’t need to breath air. They are ideal for the environment of space. Machines that can self replicate and can produce goods on demand will make the Industrial revolution look like a tiny improvement.
