Nobody has a job that can be fully automated away. Instead, they might lose their job to automation when some non-automatable parts can be done by fewer people and the remaining non-automatable parts can be made optional and the resulting cost savings are enough to pay for a machine to do the automatable parts.

Lots of tasks that could be automated with current technology aren't, simply because there's a non-automatable task that requires a baseline labor force (e.g. widget maker gets jammed once in a while, need someone nearby to remove the jammed widget and restart the machine) which then becomes essentially free when used for ancillary tasks (e.g. sealing boxes full of widgets, which also draws attention to drops in widget output volume). And sometimes humans are simply the cheaper option.

No doubt many people will lose their jobs to AI, and others will have to accept wage cuts to compete with the falling cost of automation, but that doesn't necessarily mean the AI is doing the humans' job now, or that none of the original workforce stays.
