Putting thing stogether is information. The arrangement of metal that distinguishes a pile of coal and rusted iron from tempered steel is information.

The way we usually do this is through crude processes that generate gradients that rearrange the locations of the atoms in a favorable way, and we iteratively move towards the arrangement of matter we want.

This involves the application of energy to generate a entropic gradient of the right shape, which is the only way we know how to mass re-arrange atoms into a new form.

But it is just information. Some energy needs to be added to get some states from others, but the net energy difference after processing tends to be far far less than the energy used -- most of the energy is leaked off as heat, not captured.

This leaked heat is entropy -- loose information. The ordered energy we use to induce the changes stuffs some of the information into the new structure, and the vast majority leaks off as heat.

If all the humans know is our current crude methods of infusing stuff with the structure we want, then they'd basically have to reinvent industrial civilization. Time would be measured in generations not years, as they would have to breed a population sufficient to manage the industrial civilization needed.

If they instead had all of the information they need to make it efficiently, and the ability to exactly use that information, they could literally walk around and hit things perfectly with hammers and cause them to reassemble into the shape they need.

Remember, all that is required to uncrack an egg that fell off a table is the exact right set of taps, impacts and sounds. It is the lack of information, and the difficulty in doing the actions exactly (low energy, extreme precision) that makes this impossible. The easiest way for a human to uncrack an egg is to feed the cracked egg to a hen, or compost it and feed the food you grow to the hen.

This level of knowledge and precision in action is far beyond what any human could do, but you did say the had exact knowledge on how to do it. And mere mortals have social issues. Clearly you are not talking about mere mortals, as they have no social issues.

So if each woman produce 6 children per generation, 3 of which are women, and the population is half men, after 10 generations you have ~120,000 people. After 20 generations you have ~7 billion people. I'd expect it to be somewhere in that interval without perfect information.

With perfect information, they walk around tapping things and those things reform into the exact ingredients they need. They touch them together, tap them, and they bond together. Their actions look more like magic than industry.

Putting things together is information. The arrangement of metal that distinguishes a pile of coal and rusted iron from tempered steel is information.
