The cell operator can detect that a user is moving. The operator may be able to warn the caller that the callee is moving (faster than a threshold), allowing for the caller to disconnect before it rings. Drivers should be able to opt in for this warning system so that passengers aren't affected by this check.

Valid point. With all new and popular languages getting close what was just theory some 15 years ago, it makes more sense to have a CS degree. Without CS, it is hard for developers to understand and use currying, design patters etc., effectively. I come across developers who come with a very diluted CS degree and struggle with templates (generics).
