Intolerance to memorising

I have spent the last 1 and half months (roughly) in close proximity to my grand-parents. I see that they lay heavy weightage on memorising things. Phone numbers, distances, maps, relationship-connections etc.

I see that my grand-dad prefers to make a rough draft before writing a letter or filling out an application form etc.

I remember being the same until a few months (or is it years) ago. But now, the internet equipped computer age which allows me instant access to information, editing and spell checks makes me intolerant to the erstwhile systems.

I no longer see virtue in or feel the drive to deliberately learn things by heart. I no longer want to jot down things I find interesting - recipes, songs, names, addresses - not even phone numbers.

When I meet someone interesting, I normally google or facebook their contacts.

My thinking is that the human race is slowly going to use lesser and lesser of their memory cells.

This will either make the human brain (and head) smaller over generations or it will enable the human race to sharpen other aspects of the brain - analysis, creativity, inventions. (thereby keeping our appearance the same)

What do you think?
