Technology runs on energy. Case in point:
I saw one of those YouTube videos of a person describing their shopping of clothes. Not right now, quite a while back, when living in NOIDA sec 39 in 2010-11. The wired broadband I had then was about the same speed I now hold in my hand literally. Moore's Law, manifested again? :)
Having activated Do Not Disturb for my number, I now know it works. I don't get any solicitation calls at all. Even those pesky real estate SMSs have dwindled down over the past few months. I guess they or their softwares learn to avoid numbers like mine. It gives me a sense of self-righteousness over what is fast becoming a weep-if-you-aren't-rich society. But enough philosophical discoursing. Time to try to sleep.
