I think nearly all white collar office workers will be replaced eventually. For lots of jobs, the limitation is not the ability of current models, but lack of integration to existing systems. This will change quickly, as writing new systems and integrations is cheaper than ever, thanks to agentic programming.
If the job involves mostly working on a computer, it will be probably gone in 10-20 years.
You may be right that white collar work can be replaced but I don't think it will be. Current society can't function with a majority of the population unemployed.
It's a catch-22 for the companies as well, since white collar work is presumably done because a company has customers, and most of their customers are white collar workers. At least in the US and Europe.
