Our oil problems are only going to get worse. Our trade balance is only going to get worse. So we have to slow the growth of U.S. oil consumption, particularly imported oil consumption.

The way things are going, we are not too far from the day when it will take an hour's labor just to pay for the gasoline to get to the job.

So we in Congress have a very clear choice. We can take largely symbolic action and sit back and fiddle while Americans burn more gasoline. Or we can pass concrete, effective legislation that will save consumers money while significantly reducing U.S. oil consumption.

But our energy woes are in many ways the result of classic market failures that can only be addressed through collective action, and government is the vehicle for collective action in a democracy.

We must address, individually and collectively, moral and ethical issues raised by cutting-edge research in artificial intelligence and biotechnology, which will enable significant life extension, designer babies, and memory extraction.
