I Have Something to Say

So we can put a man on the moon, we can calculate distances to billions of light-years, we have built pyramids, great walls and space ships.

All of these great feats... but we cannot stop telemarketers from calling our phones. 4 house calls so far today, others to my mobile... I'm on the laughing-joke "DO NOT CALL" list...

Surely this can't be as hard as the eradication of smallpox?
