That is another alternative to the fate of intelligent civilizations.

1) They might keep going upwards and decide to do something else than
spam the galaxy.

2) They might get control of their pleasure centres and exit to nirvana.

3) Intelligence might peak and then dwindle away as it ceased to be an
evolutionary factor.

Your suggestion 3) has support in that people are delegating more
intelligence to their devices nowadays than ever before. One article
commented that we used to casually remember dozens of phone numbers,
but we have lost that ability as our phones do the remembering. We
used to do mental arithmetic to add up bills, calculate percentages,
etc., but not now. We used to read maps and plan journeys, but now we
just key into the GPS system. And so on....

People think spending hours updating their status and reading and
commenting on their friend's status is a significant activity.

Actually, in some ways it might be. I note that Obama thinks that
because hundreds of terrorists have tweeted and posted Youtube videos
claiming the Assad military gassed civilians, that constitutes real
evidence.
Can a few thousand 'likes' really start a war? What a strange world we live in.
