It's been my life experience that none of what you hear is "in demand" actually is, what it instead translates to is "not willing to pay or hire or train enough".

My friends who work in nursing tell me it's not that there isn't a talent pool, it's that they are short staffed due to hiring limitations more than lack of interest, which then feels like being short staffed because everyone is putting in more time, which makes the environment suck, which does make people quit, especially exaserbated with covid and conspiracy theorists treating them poorly. But until the underlying issues are solved, it's not a real shortage as there are qualified people looking for work but not being hired.

Teacher shortage is similar, not willing to pay them enough(even when school funding is high, teacher pay stays low), and the amount of bullshit they have to put up with seems to go up every year, which is unrelated to amount of people with teaching credentials.

Programming has a similar problem, every company wants senior roles but very few are willing to train, so it's a bottleneck more than a shortage.
