Freeing your brain from the burden of memory frees it up to do things like search and crosslink. I accomplish more and faster with Google than I ever could with my memory. I don't even bookmark pages I find, 'cause I know I can find them again later.
I used to remember phone numbers, now the only ones I remember are my work and my mobile, and only 'cause people ask me for them all the time. I mean, who even uses a phone? I'm more likely to remember an IP.
I don't need to remember things, I just need to remember processes. I know how to find the information I need, and I know how to assemble that into a larger whole with the other things I find. Short term memory has become medium-term: It's there just long enough to finish something, and if I need to come back to it a year later, I'm learning it all over again. But fast!
I don't remember PHP commands. I remember where I found them last time. I don't remember phone numbers, I remember how to work my phone, and I intuit how to work someone else's if the need arises. I don't remember passwords, my browser does that for me and I remember how to reset it if the browser breaks.
It's all about the processes.
