I'd say biggest displacement would be in
IT,
Insurance/Financial Services,
Creative,
legal,
Thats not even 10% of the work force
and it would prob. take a decade for it to fully play out.
So too for complex accounting/insurance structures.
Under the BLS classification scheme, these jobs are sprinkled around under various industrial categories such as medical, logistics, business services, etc. they add up to a large number of jobs in the aggregate (probably another 10%)
