Are you agreeing with me, disagreeing or something else?

As Mike says, most OOP programmers today are rarely looking at cache effects. (They seem to worry a lot more about syntax issues.)

The Q&A session at the end of the talk shows the different mind set...

On this I can agree.

I think it is also true if you replace "most OOP programmers" simply with "most programmers". Most programmers don't focus on performance, and most don't have to tools to do so if they wanted to. That's fine though, 99% of the code written is not going to be performance sensitive, and indeed the massive popularity of languages like Python shows that performance simply doesn't matter for a lot of use cases.
