During the industrialization, machines did not replace all jobs, but they replaced or changed most jobs. The same will happen here.
A typical office job will have a few hours a week of actual, intensive thought. The vast majority of time will be spent doing simple, repetitive work. This work can be automated, or at least significantly sped up, using technology like GPT.
“write an API client for …”, “integrate APIs … and …” can easily be automated. Yes, you'll still have to write the business logic, but that's not the majority of your work today. You could even have it write unit tests based on the JIRA ticket description.
The same applies to many other jobs.
