already 20 years ago I met a guy (masters degree, university) who never freed dynamically
allocated memory. He told me he is 'instantiating a object', but had no idea
what an heap is, and what dynamically allocated memory means.

I'm still astonished at the constraints
those guys had to suffer:
PDP-7 Unix provided a multitasking environment by dividing the 8K
words of memory into two halves. The lower half of memory was
reserved for the kernel. The upper half of memory was set aside for
the currently running process.
But you try and tell the young people today that... and they won't believe
you.
Don't even get me started. Young people think that a VM is a server.
I wrote a microbenchmark suite, lmbench, and I get people sending me
email that they get inconsistent results on their VM.
The lack of knowledge that would make someone ask about that is stunning.
