I kind of disagree. It’s not like people are printing out or even reading back that far. May as well include it, but certainly don’t expect people to read it.
I’m currently hiring and reading a lot of resumes. I rarely read past the first 2-3 pages, but sometime when I’m curious go back to learn more about career path. Has someone been programming for 30 years? Or started as a dba or a support tech?
I think it depends on the risk of including it. If you worked for an embarrassing employer or maybe don’t want people to guess your age, remove old stuff. But otherwise, I suggest just spending more effort on making the first page relevant.
