Thus, a continuous wave is incapable of conveying any information. Um, not quite:-) The very presence of the CW signal conveys SOME information (e.q. the fact that something is out there generating it:-) It's the turning on and off of the wave that conveys most of the USEFUL information:-) Which makes CW communication a DIGITAL mode, by the way.
