After my previous comment it occurred to me that a comment of yours may have been sent to spam accidentally at this site, thus red-flagging your e-mail address. “Touch to Click” is a menace to any moderator; it’s so easy to brush a touch-screen with one’s finger when the doorbell rings or whatever, and not even notice. The implications for banking, governmental and defence systems are deeply worrying. Could such a triviality even be the answer to Fermi’s Paradox?
