I strongly disagree :)
CalVer is 100% accurate, conveys information that's highly related to what I want to know when I'm looking at a version number (how outdated is this information or software), and dictated by Pope Gregory the 13th.
SemVer is only as accurate as the release manager is clairvoyant, conveys 0 information with a single version number, and is dictated by the marketing department.
