Why is it that noone notices anymore how amazing it is to be able to talk to ppl around the world through im?

People that would've never met before the advent of the internet are now meeting, and talking in real time, take or give a few seconds. Letters are now instantly deliverable to whoever u want it to be sent to, when before, it took days, weeks, or even months to get to them through snail mail. why are ppl so non-chalant about this?
