Tech recruiters: maybe there are a few tolerable ones. In 2012, a recruiter proclaimed to me that Golang was "irrelevant" while having zero understanding of technology or the industry. I thanked them and marked their emails as spam.
Another funny (or sad) thing - getting messages from recruiters with job recs saying you should have at least 5 years experience in Swift/React/whatever when the technology was just coming out.
I should send out fictional resumes for social research of the form:
Senior full-stack engineer with 25 years of solid experience in React, Elixir, and Rust running production stacks in the real world.
