Which is somewhat akin to downloading one today. If, however, that same kid started small, with a data model, then added calculation, and UI and stepped through everything designing, reviewing, and testing as they went, they would learn a lot, and at a faster pace than if they wrote it character by character.

The thing is, any generation can say something similar. Just look at the article: it manages to produce and describe the creation of a simple spreadsheet, yet the code and accompanying description would only fill a small pamphlet.

There are various reasons for that, and those reasons extend beyond leaving out vital functionality. While C is archaic by our standards, and existed at the time VisiCalc was developed, it was programmed in assembly language. It pretty much had to be, simply to hold the program and a reasonable amount of data in memory. That, in turn, meant understanding the machine: what the processor was capable of, the particular computer's memory map, how to interface with the various peripherals. You sure weren't going to be reaching for a library like curses. While it, like C, existed by the time of VisiCalc's release, it was the domain of minicomputers.

I mean, can the current generation truly understand the craft when the hard work is being done my compilers and libraries?
