Cringely on shooting at a moving target

Years ago, tech guru/writer Bob Cringely realized that the large amounts of energy use required to store data on hard drives would be a limiting factor on the growth of the tech sector. (Where have we read about that before?) So he had an idea to replace the glass media in conventional hard drives with much lighter metal foil, thus greatly reducing energy use. In a recent column, he writes about how market changes and advances in other technologies (read: cloud storage) have challenged the effort to bring his innovation to market:

While what we wanted to do was possible it wasn’t practical. Operating on that bleeding edge it was becoming clear that most of the blood would shortly be ours. It was time to either give up the dream or make a quantum leap in manufacturing what many already viewed as a technology that was itself obsolete.
