Science

I used to watch a TV show called "Beyond 2000" in the 90s. They featured brand new breakthrough technologies that were so cutting edge that normal folks wouldn't see the tech for years. One of the technologies they featured was solid state storage (SD cards). I remember thinking how fantastic that would be. Now we all walk around with them in our pockets. Point is, it's cool to get a glimpse of what might be coming down the pipeline.

I always take several years for new storage technology to go from the lab to public computing devices, if it even makes it out of the lab.

It's safe to bet that 3/4 of new tech advances of that sort have serious limitation that are deal-breakers. And the rest takes at least 5-10 years to become mature and cheap enough so that it's accessible to average folks.
