If the guy that invented sms patented 140 char messages there would be no twitter. Or irc messages, or smoke signals, or X where one people sends a text message to others.
Patents are a bureocratic perversion that do not acomplish any progress to humanity, they just perpetuate the bureocratic system itself.
Many of these humans are caught within a system which incentivizes personal interests over those of society. Those in higher power are aware of this, but too cowardly to do anything about it, sadly, and the lower amongst us are forced to at least protect themselves from a broken system. But the thing is, the more they protect themselves, the more this corrupt system becomes reinforced and innovation becomes even more endangered. We need to wake up and say enough is enough already. Do we really want this paralyzing system to dictate us and future humanity?
