No, I was asking it in a very casual, no serious way.
Of course, how else are they going to make a living if your local Joe has the same tech used by a multi-billion dollar company?
No necessarily, that's why R&D in industry is more unstable compare to other branches [in terms of job security]. For one idea that make its way to the market, 100s, even 1000s of ideas fail. Not all tech go in the simple fashion of industry use then to average Joe use.
You can have technologies that have mass industry appeal but little average household appeal, and vice versa. So in terms of average Joes like us, there is little point in talking about the "age" of a tech by looking at when it originated in the industry - since, while true, it's also rather pointless, since many tech used by the industry never make their way into the average household use.
