I dont think starting startups gets cheaper.

The whole essay is based on this idea. But Paul gives no reasons, why there should be a such a trend.

Moore's Law, open source, more abstract languages, the web for promotion. (I believe this list is in the Wikipedia entry for YC.)

Hardware development, prototyping, and testing is cheaper for a number of reasons.

Cheap CAD tools, cheap custom boards, processized manufacturing.

Most people drastically underappreciate how much China has helped innovation in this regard.
