Hi, Richard,

There is a new 3D process that, apparently, creates a mold into which a liquid is poured and then hardens.  Does this process sound familiar?

Hi, Steve,

I am usually suicidally optimistic in many situations, but in this case I have felt a bit of "bubble-sell" like back in the dot-com days.

I was surprised to see this article from INC reprinted in Business Insider:

I'd like to say "for now" because if we spin around and wait 20 years it might come back, but now is not yet the time.

As an aside, in the early 1990s, my father asked me if he could get a scanner and scan and store many of his archives on his computer. When looking into it then, it was daunting and imagine what a few TB of storage would cost back then. Even today, it takes someone with more computer experience than my father would ever be capable of mustering. 
Heck, while I'm not a computer expert, I find that if something goes wrong on a large storage device, I need to call in the experts.

That said, once I got a replacement unit, my now-six-month-old QNAP
TS853 Pro NAS unit has been wonderful. I have eight 3 TB drives in it configured as RAID6 providing about 18 TB of storage, of which I'm currently using about 60%. (used 8.8 TiB, available 7 TiB) When you're in the TB range the difference between TB and TiB starts to become large!

I provide this example because over a space of two decades what was impossibly expensive now only costs a couple of grand... and I get close to wire speed on my Gigabit Ethernet into and out of the thing (when the computer at the other end can handle it).
