I think actuary is a poor example. Graeber himself would might correct himself if he was reminded of what he just said. It's probably a waste of time to hone in on that particular off the cuff statement.

There are still plenty of jobs which are bullshit though. For example my girlfriend is an auditor. Most of her job would disappear if the infrastructure existed to have her clients financial records completely digitised. A program could then analyse the data (which is mostly done at the moment with a bunch of spreadsheets right now) and with higher audit coverage (they can only check/test a fraction of records and transactions). Her workload could go from 5-6 days a week to 2.
