Earlier, Harry had very secretly—he hadn’t even told Hermione—tried to Transfigure nanotechnology a la Eric Drexler. (He’d tried to produce a desktop nanofactory, of course, not tiny self-replicating assemblers, Harry wasn’t insane.) It would have been godhood in a single shot if it’d worked.
Now, try to imagine Chapter28!Harry—after learning to lose, but before going to Azkaban and reconciling with his dark side—attaining “godhood in a single shot”. How well do you imagine that might have worked out?
(This is leaving aside the myriad ways this scheme could have gone horribly wrong, of course. The point is, even if everything went according to plan it most probably would have been a Bad End.)
How would successfully transfiguring nanotech be bad, exactly?
The bit I’m referencing is from Chapter 28:
