Perhaps we have differing definitions of "technical workers" ? Here in the Bay Area at least there are a number of companies which are replacing "senior staff" with an LLM and a junior engineer. The argument is that this combination is "cheaper" than the salary paid to the senior engineer. For me that is exactly analogous to replacing a factor worker with a robotic work station and a technician to maintain the robot. There is a ceiling on that junior engineer's career which occurs when they are themselves replaced by another junior engineer to reset the salary cost.

We've seen some of them post "Ask HN's" about what they should do now because they aren't getting callbacks or any traction on their job search.

What I haven't seen yet is this replacement penciling out to actually be less expensive when you look at time to complete tasks and support costs from faulty code/designs getting fairly far into production before being re-tooled. That may turn out to be endemic (at which point the replacement will stop and the trend will reverse) or there may be developments that mitigate these costs and get the combination to be more cost effective. It's something I watch for, evidence of it going one way or the other.
