We don't even need AGI at this point to do that. Most jobs (emphasis on most) that can be done sitting in front of a computer can be done by something like chatGPT3 or GPT 4. Or atleast make one worker productive enough to drastically reduce the number of employees.

Similarly self driving and other similar automation may be able to reduce physical labour jobs but that's most likely going to require AGI and advanced robotics.

At this point white collar office workers seem easier to automate than even bus and truck drivers.

Also, once this wave of automation starts in offices, "bullshit jobs" will be wiped out.
