Interesting discussion. Reminds me of the &quot;why would I ever want a computer?&quot; discussion I got from folks back when I was in High School when I showed them a computer I had assembled from a kit.<p>And realistically they didn&#x27;t need a computer ever, they needed a smart phone. Although for a while they used a computer and complained bitterly that it required too much maintenance and had a steep learning curve.<p>So here we are in the 3D printer &#x27;nadir&#x27;, the period of time between hype and wide spread adoption. The thing is, 3D printers have gotten <i>much</i> better since the first rep raps were trying to print their own parts. And with that has come more applications, and with that more fun. A 3D printer is the ultimate expression of a Lego set these days.<p>Once I had internalized what I could do, which I could not do before, the number of things I started printing went up dramatically. And so much has been learned and developed in terms of how to best fabricate things in this way that what used to be hit or miss can now be rock solid. For example I doubt I will ever buy a project case for a gizmo ever again. Holders, jigs, struts and braces, all are &quot;need one? print one&quot; these days. But if you aren&#x27;t a maker, if you didn&#x27;t write any code on any laptop you owned, if you really just want someone else to do the fabrication, then yes they are not for you at this time, you&#x27;ll still use a service. But that will change, I hope a bit faster than it has, the first 10 years have not moved along as fast I would have liked.
