Age Ain't Nothing But A Number...That Microsoft's How-Old Apparently Can't Get Right

The Internet is pulling double-duty as both an ego crusher and incredible time suck with the debut of Microsoft's age-guessing tool, How-Old.net.

The age-guessing website lets users upload a photo and then feel incredibly flattered or terribly offended (or, just really, really confused) as it guesses at the age and gender.

How Old <em>Are</em> They?

How-Old shows Microsoft is venturing into the domain of machine learning -- programs behind self-driving cars, speech recognition and search prediction -- the way companies like Google and Facebook have.

The tool has already become a huge viral hit , which may be an important boost for Microsoft in the middle of its Build conference this week.
