Those kind of resumes where you have like 18 years of work experience in 9 different language, but you were essentially not much more than a junior dev in any one of them, are very unimpressive.
That is the typical career story and that's why a lot of people struggle to find dev jobs when they get older because they weren't managing their career and were just riding the technology churn with all the other 23 year olds.
You should think of your career progression as every couple of years you are making a jump up to either more responsibility, or a more difficult domain, or working on systems with more load etc ...
If you don't make these forward progressions you will be judged harshly as an older person, because it's very difficult for people to NOT think, "well why didn't this person make any progress in their career? They must suck."
The technologies used is a side detail, it's never the "meat" of your work experience.
