I think it all gets down to how one defines a "Golden Age".
For me, I define it as a time when Innovations in Design yield Significantly Meaningful Improvements in Functionality. Consider the Personal Computer.
In the IBM 8088 days, just being able to run a Spreadsheet or Compile a FORTRAN program on a desktop was amazing. When Windows for Work Groups hit people were Blown Away. Hardware and Software developers scrambled to bring to market Ideas which Exponentially Improved the ability of the PC.
Then Windows 98 & Windows 2000 arrived. Truly this was the "Golden Age" of Personal Computers. Advancements were being made in Speed and Functionality in 10 Fold Leaps. Would it ever end? Had we reached the Pinnacle of Functionality?
Most said No but many said that Windows XP was the "End of the Beginning". Because after Windows XP, Significant Improvements declined.
Vista was a Train Wreck. And Windows 7, all be it with much Nicer to Look at, yielded Very Few Significant Improvements over Windows XP. Some would say, Myself included, that more functionality was lost with Windows 7 than was gained. The "Golden Age" of Personal Computers was over.

I think the PC analogy works well for the e-Cigarette Industry. Sure, New Products hit the Market every week, but are they really New Designs? Do they Significantly work Better? Are the New Products Easier to Fill? Do they Last Longer?
Unfortunately No. For the Most part, the small Tweaks we see to Existing Designs yield Very Little Significant Improvements.
Not to say that All Future Products will just be "Clones" of Existing Designs. But as a whole, I think the Truly Innovative Ideas will be Very Seldomly seen. The "Golden Age" of e-Cigarettes has Pasted.
Now, Unfortunately, we are entering the "Taxation/Regulation Age".
