That's a forced analogy which doesn't quite work.

I've been thinking about this topic a few months ago when considering how I go about finding out information on how various things are implemented in the Linux kernel, as someone that's not a kernel developer:

* option A is that I start by reviewing the literature (most books are quite old, but I might get lucky) to get a general idea about the topic e.g. memory management under memory pressure. Then I search the kernel docs. Then I use any references that I found to e.g. LWN or similar websites. Message groups search. Finally I would do general internet search, SO, etc. In between these steps I might look at sources, although that's hit or miss, depending on the specific topic. At the end of this adventure, I will probably have a vague or middling understanding of what I was looking for.

* option B is that I ask our kernel expert and he tells me what I want to know, because he's continuously read all of the above resources for the past couple of decades.

So not only is the human memory not obsolete, it is daft to think that Google - which is getting amnesia to boot - could "upgrade" it.
