Companies that have already invested in big machines or equipment that need humans to operate will move to full automation very slowly. If a company just bought many human driven trucks it'll take them long time to switch to fully automated trucks or to upgrade already purchased ones. If a manufacturing plant has been designed with human workers in mind it'll take time and more investment to get full automation. And we're still long way from affordable humanoid robots.

On the other hand if some simple AI cloud subscription could automate the work of an office worker, call center worker, accountant or programmer, that would happen a lot faster.

IMHO office jobs will start getting automated on a large scale in a few years. And a lot earlier than truck or bus drivers.

Aspirational jobs that require a degree and student debt are more at a risk than manual labour.
