There is a feedback aspect that this article does not seem to get.<p>> After all, the <i>material</i> hasn't changed (much), so if the calculators were good enough for us 10 or 15 years ago, they are still good enough to solve the math problems.<p>Technology <i>changes</i> the material: it changes what you think you need or want. You could almost say dialup internet was fine for viewing text web-pages -- why does it need to be faster? Broadband enabled web video -- which in turn spurred the need for broadband.<p>The calculator example looks a bit like a phone. If you took a phone from 2000 and one from 2007, they would look pretty similar. It is still a phone, is it not? We do not <i>need</i> something more, do we? And then the iPhone appeared.<p>> Here's the thing. Some technologies don't change all that quickly because we don't need them to. . . . Look at cars or power plants<p>Crikey! If you wanted to hit on two of the things we <i>do</i> most need to change, and have for decades, it might well be just those.<p>The whole article disturbs me a bit, actually, because it seems dangerously full of the anti/un-creative mindset. You will never invent anything if you just look at what you have and think of justifications for why everything is pretty much fine. You create by <i>finding</i> faults and imagining what you do <i>not</i> have. Look at those two calculator pics, and think of them as representing some part of the web now and in 2021. Scary? Well that is what it <i>will</i> be unless you get irritated and make some weird unexpected new stuff!
