You conflated statements. You were (and still are) putting words in my mouth.

This statement [of mine] :

> Application level tools do change quite fast. The fundamentals of technology do not.

Was in response to your blanket assertion that technology changes so fast current knowledge will be useless in 15 years.

I believe this claim to be false, and provided evidence to that effect. You then claimed I had claimed this knowledge was unique among older engineers. I said no such thing. I don't even know how you would get that impression. I cited current University courses, after all.

As for our previous discussion on ageism, I think it's clear we won't ever see eye to eye and will have to agree to disagree.
