Powers As Programs: With the availability of mnemonesis to download knowledge and skillsets into your brain, gnostic overlays to do the same thing for professional personalities, and the ability to download recipes for your portable nanolathe or desktop nanoforge to build you the tools to use them…

…yeah, this is pretty much the way it works.  Although those powers which require genetic changes, large tools, exotic materials, or significant ‘shell modification are somewhat more difficult to achieve.

But see also Skilled, but Naïve, when we get there.
