I've watched debates on this topic for almost two decades and they never seem to go anywhere. People who believe in supernatural entities tend to justify their beliefs through less logical arguments, and people who do not believe in them have logical reasons to support their view; ergo there's no satisfactory middle ground - there's no common language between believers and non-believers.
This is a case of a belief that'll die with their adherents, as new generations seem to hold less superstitious world-views than their parents. Hallelujah to that.
“So although you might not really notice the problem after one year or two years, after five or ten years it can become a huge problem,” he explains.
This area definitively warrants further research - if nothing else, it could mean that Iris scans will have to be re-done every 5-10 years (a bit like passport renewals). Depending on the specifics of the cumulative degradation (i.e. how exponential the effect is), you could be looking at a 2,000,000% failure rate increase in 11 years.
The only bit which rang a bell FTFA:
Based in San Diego, California, MP3tunes was launched in 2005 by Robertson three years after stepping down as CEO of MP3.com, which was also founded by him.
The medical industry has been using 3D voxel based imaging for a long time now, and this looks like a neat extension of existing techniques. The output looks quite grainy but this is probably partly down to kinect resolution, and partly down to compression. Based on the video my guess is that the voxel resolution is somewhere between 128x128x128 and 256x256x256 so worst case you could be looking at 10x more data than HD video at full frame rate.
This looks like a great little R&D project, but one has to wonder what the best market for this kind of live 3D videoconferecing would be - perhaps getting feedback on your golf swing or dance steps by a remote coach? It likely won't come cheap, and a decent (say 10 Mbps) network link is almost certainly going to be a requirement at both ends for decent performance.
Blessed be those who initiate lively discussions with the hopelessly mute, for they shall be known as Dentists.
