Why do we insist on using computers to do everything? Things that are already easy. Things that weren't even problems that needed solving until we realised how hard they were for computers to do. Maslow said that when all you have is a hammer, everything looks like a nail.
What we have is a world where every eighteen months, the hammers can hit twice as hard as they did before. So even things that didn't look like nails in the past, might yet be persuaded to yield, if only we hit them a bit harder.
Using computers to recognise human faces is like employing a human to do your arithmetic for you, instead of a calculator. It's a gross misuse of talents. The human brain is the most sophisticated facial recognition device that has ever existed.
It is possible that one day, we (and by "we", I mean someone that is neither you nor me) will build a device that exceeds our own natural talent in this regard. But at what cost? And to what end?
We aren't busy perfecting robot earthworms to digest leaf litter because we already have actual earthworms that do the job perfectly well. If Microsoft replaces the receptionists in its offices with a web cam and a digitised face, what exactly have they achieved?
They have taken a job that can be done by virtually any human to an extremely high degree of competence, including coping with visitors wearing large hats or the outbreak of unexpected building fires, and replaced it with a computer that will only order you a taxi, if you spend 10 minutes patiently navigating your way through voice menus.
Yes, I know you won't need to pay the computer - but you will need to pay for the computer and you will certainly need to pay the team of 20 sysadmins it takes to keep it running. Holidays are just replaced with essential system maintenance, sick leave with the Blue Screen of Death. In the end, all you have is an expensive way of doing the same job badly.
And if that's all they want, they could just as easily hire me.
