Yep.

'116. You think you know when you can learn, are more sure when you can write, even more when you can teach, but certain when you can program.'

Of course, machine learning algorithms render this obsolete. You don't have to understand something to program it, just have a vague understanding of how that understanding might come about.

Arguably, that's still understanding. 'Now I know that natural language parsing is in this family of parametric functions which my ML algorithm can handle, with the coefficients given by minimizing the divergence from a bazillion word corpus...&etc.'

If that could work, that would be equivalent to having a Level 3 understanding of how to regenerate the required knowledge -- hardly a shortcut!

No, you have to have a certain understanding of how that understanding might come about.
