Holographic Discs!!!

Wow!  Holographic Discs!  It sounds so exotic and new and high tech!  But really, the technology has been around for decades.  But only recently did GE make a breakthrough in holographic technology that would allow CDs to carry enough information for about 100 DVDs.  This technology, once made market viable, will bring about the obsoletion of Blu-ray, a technology that is still gaining momentum.  It's a testament to how fast the technology market moves.  Not only are we gaining new technology at an amazing rate, that rate is actually increasing!  Why can it store so much more than a regular disc?  Well normal CDs and DVDs only store information on one layer.  They have a metal layer on their surface that hold all the information.  This new holographic technology forgoes the metal layer and instead uses the full disc to store information.  This disc is much cheaper per gigabyte of storage than even Blu-ray.  Blu-ray debuted on the market at around $1 per GB, and is now down to around 50 cents/GB.  Currently, the GE disc disc is around 10 cents per GB, a fifth of the cost of Blu-ray.  So we have the obsoletion of Blu-ray on the horizon.  Even for someone growing up completely in the computer age that has never lived in a house sans computer, this seems to be moving fast.  I can only imagine the disorienting effect this might have on older people not used to things developing this fast.  For example, my mother is still getting used to having a separate box for cable instead of just having a TV.  I imagine many baby boomers are in the same boat as my mom.  But just because a lot of people can't keep up doesn't mean it's a bad thing.  On the contrary, things like this make me optimistic towards the future of humanity.
