Other than people needed to write code for tech startup/apps/etc, are any of the other “hard” engineering sciences really in a short supply? (EE/Materials/Chem/Mechanical/etc?)
One thing I think is that companies also aren’t interested in training or have folks learn since everyone has a short term focus IMO so if your skillset is hot/in demand now, there is a shortage since it’s a new area, but most folks who have graduated and worked a few years are being passed over.
This is all my wild guess/speculation though.
With less trading on wall street, I’d assume math and physics types are in a slightly lower demand as well.
