I've been in the industry long enough to see the jobs you talk about in the office. Many don't require a "profession" and yes these are up for automation unless there is some other moat (e.g. locality or the personal touch for sales staff for example). The "Software Engineer" is grouped now with such people - general process office workers once their differentiating factor (i.e. skill difficulty) is trivialized by AI. The fact that it is paid more than those general jobs just makes it more enticing as a target.

Most engineers, even accountants, any profession with a title really that required some study usually have the moat of liability and/or locality. SWE's don't really have this in general - a unique job that while requiring a degree for many high tech orgs, will be the first to go. As you said 80% is enough for many domains here. Any other engineering profession (e.g. electrical, civil) has other moats that mean they won't be as disrupted.

Most of the people I talk to w.r.t this issue studied in general professions or trades, physical jobs. i.e. SWE is especially affected especially at the higher end where study was required because for the same "effort" of a CS/Engineering degree you could of been in any other profession where there was more protection from AI (bootcamps aside). AI may have the CS/SWE university pathway be redundant - ironic if most college/uni jobs are still safe except for the industry that birthed the AI in the first place.
