You are correct about that, but we still need a little time for bandwidth speeds and connection issues to mature. In the meantime flash media enhancements can be funded through app/games that everyone does pay for. Instead of hoping someone simply needs the tech for data storage.
If they were available, I'd be using them already. Because it is true, optical disk are far to volatile for a permanent solution. I use optical storage only for a secondary backup to HDD storage. The only reason I am using optical storage, is because the industry is intentionally not using any potential solutions to bring the price to flash storage down.
