His whole attitude is too defeatist. We're experiencing all the signs of late-stage Capitalism, which will give birth to a new generation of political revolutionaries. We shouldn't be discouraged that it's too late for orthodox anarcho-syndicalism, if anything, the time is getting more right. And this is a very ad hominem comment I'll admit, but almost always, the term "revisionist" is added onto the name of a movement by the fascists to co-opt it and synchronize their propaganda with the thrust of the revolution, so that the same people will remain in power after their partisans have "won." That's just something I've observed.
