</div>That is another alternative to the fate of intelligent civilizations.<br>
<br>
1) They might keep going upwards and decide to do something else than<br>
spam the galaxy.<br>
<br>
2) They might get control of their pleasure centres and exit to nirvana.<br>
<br>
3) Intelligence might peak and then dwindle away as it ceased to be an<br>
evolutionary factor.<br>
<br>
Your suggestion 3) has support in that people are delegating more<br>
intelligence to their devices nowadays than ever before. One article<br>
commented that we used to casually remember dozens of phone numbers,<br>
but we have lost that ability as our phones do the remembering. We<br>
used to do mental arithmetic to add up bills, calculate percentages,<br>
etc., but not now. We used to read maps and plan journeys, but now we<br>
just key into the GPS system. And so on....<br>
<br>
People think spending hours updating their status and reading and<br>
commenting on their friend's status is a significant activity.<br>
<br>
Actually, in some ways it might be. I note that Obama thinks that<br>
because hundreds of terrorists have tweeted and posted Youtube videos<br>
claiming the Assad military gassed civilians, that constitutes real<br>
evidence.<br>
Can a few thousand 'likes' really start a war? What a strange world we live in.<br>
