There isn't any hope for Linux on the smartphone, at least not Linux as actually intended in the talk.

A proper solution needs to run perfectly on users' existing hardware or it won't be run at all. There are a lot of old unupdated devices which should be ripe for the picking. The only solution close to matching the OSS community's resources is the Android kernel for all of its problems. The Linux smartphone community is way too ideological (far more than even RMS was back when OSS started) to do it - they won't use Android, and their hardware would also be way behind for similar reasons.

So irrelevance it is, unless some rich sugar daddy company decides to make an entrance to the smartphone market, but I don't see any plausible contenders.
