My specific example - sourcing "real time graphics experts"- was a bit obscure. It's a niche. The first problem arranging training would be to first figure out how to train and by whom. A learn-by-doing projects of increasing complexity from raytracers and scheme interpreters to a real time 3D engine and shader languages would probably do part of the trick. Then add 3D modeling and some drawing courses to make sure they appreciate the art as well. Doable in two years, full time - yeah sure. But what are the economic tradeoffs? The personnel to arrange all of this is available in Helsinki area. The problem, I think, is that the quantity of people sought is so small that it would be harder to arrange all of this properly than just headhunt for them around the world. It would be awesome, though. There are trainings for people like SAP experts. The curriculum is fixed and the problem domain fantastically constrained. In this case it's fairly easy to retrain for sought out skills - especially if the number of new experts is counted in the hundreds. I have to strain once more that my example was obscure and for a specific, fairly small niche. I have no idea where the thousands of missing specialists are needed. Probably for usual backend/frontend development, would be my guess.
