We wouldn't even think of makoing the jump if we didn't have real job offers in hand. Making that happen takes a lot of time (many months), and lots & lots of networking, no matter where you decide to look. Been there, done that, got the scars to prove it.
And I think our degrees would transfer over fairly easily, with no additional national certifications that I can think of (as opposed to, say, the health care or structural engineering fields).
If anything, age would be our biggest problem, since we're both over 40.
But hey, there's the overwhelming possibility that this is all just talk. Things may not become as awful as we fear.
Like everyone else who's gawking at that orange-hued buffoon, we just don't know.
But we have NOT ruled out such a jump.
