There are many deep specialties that no one picks up with "extreme speed" no matter how technical they are, certainly not to the level required by companies that want to hire these skills. Think database kernel engineering or non-trivial parallel systems design. Acquiring these skills happens almost exclusively by apprenticing for years with real experts. In six months you could go from no skills to mediocre skills with a lot of training, but no one wants "mediocre" working on their database kernel for good reason.

It would be like me assuming that I, a broadly competent technical expert, could quickly and easily develop a deep expertise in e.g. high-performance graphics engines. A diagnosis of Dunning-Kruger would not be incorrect were I to make such an assertion.

This is not a new problem.

Look into it’s history and Walt Disney has been training animators for decades. It’s a deep skill that is takes significant time to master, so you need an actual pipeline.

Continuing the idea, NASA trains astronauts. They don’t need very many world wide, but they need a few and the only way to get them is to train these people.

I could go on, but outside of a months to few years for absolutely new fields shortages are by design.
