Web development in the 90s and early 00s was not a practical substitute for learning how to program. Now, it is.
You make a claim that the low-level nature of the calculator programming was an enticement to you. That may be, but I would hestitate to generalize based on your own experiences. I would suspect that the ability to come up with something that actually does something conventionally interesting trumps the benefits of working close to the metal, ESPECIALLY with young, novice programmers. A few hours of hacking in assembler and you may get to hello world, whereas the same amount of effort in javascript might net you the ability to drag and drop objects around a UI. Which is more impressive to a kid?
