It's quite clear he does not think he himself will change everything. He clearly calls out for people to start participating in the political system in a more active way. He also doesn't say that technology doesn't have a place in change. He's saying that a lot of people think that technology on its own will fix things.

Using a war metaphor. Technology is an attack on the rear, politics is a frontal attack. He is merely saying that basing your whole strategy on rear attacks is misplaced.

Not saying anything about the truth of what he's saying, but it's clear that you're misrepresenting him here.

And using Sunde's now quite distant past together with a rather stretched out notion of tax to discredit this message is pretty weird.
