65 Years ago (when I was six) I was trying to decide, with all the stuff I could learn, what I should put my energies to. In the first instance what was, if not a waste of time, an endless trip down a hundred rabbit holes (not everything as I see it now, as context arrived long after). That if there was some scheme that was someone’s conjecture, no matter how smart they were it was just that, opinion, and a thousand opinions were as one. You would not really know, so anything that fell into that category, if not ignored at least was not a focus.
The Second area I thought of as Fads, that you might know it well but in a few years nobody would care, and again the effort would be wasted. I did not realize until too late that most computer programs fit this description, as anyone with great skills in Fortran can attest. or my own abilities in LISP
The one area I really liked even then would be called Scientific understanding, though I did not think of it that way at the time, only that everything learned would still be true years later, and understanding some things gave insights into other seemingly unrelated things.
Over time my simple way of dividing things got more complex, and much that I did not care about knowing I learned anyway. But the start till molded the rest. (bear with me a bit as I try to say where I am going with this)
Economics always seemed to be the ultimate case of opinion, just shy of astrology, but much was needed to think about just to get along in the world. However, where Economics as I badly understand it looks harder at the people and gets very generic about the products, I got to looking at the products and more generic about the people. and in doing so came to several kinds of product.
The Financial folks hold and operate the Capital and think themselves very if not most important, but what they hold is POWER that they can make the decisions, and they charge dearly for the grace of deciding in your favor so all the wealth that flows to them (and gives them still more power) must be paid off the top of all production they decide to benefit. In the net, they cost Society far more than they produce.
At the next level, you have the service sector, that is necessary maintenance to keep everything running but the value to Society is ephemeral, like getting a haircut, certainly needed but next week or month will be needed again.
Food and other commodities are a similar case as they are a necessary cost but equally ephemeral as they are used and gone.
At the next level is actual useful “stuff”( some discretion is needed as the costs of maintaining it even to physical location and the overall value favors quality over quantity) but even an umbrella stand could be doing its job with grace and beauty for a hundred or more years and many generations far beyond the expense of creating it
At the highest level (and here the Glowforge comes in) is the machinery to make the stuff of value. While an item of value might provide service for many years, The Glowforge is a Font of things that each can provide value for many years.
Thus while Classical Economics tends to add up the price of everything, giving each thing equal weight, at the end of a period of time, the combined wealth of the society will have very different outcomes depending on which end of the list is favored
So the point I set out to make is that the Glowforge empowers creativity to make ideas real and make the world a richer place than if they did not exist, and a hundred years from now, things made on a Glowforge will still be cherished treasures, no matter what else happens in the World.
