this reminds me when I was learning programming. I was talking about it to my granddad (that pioneered a few things computer-related), and he asked me "okay great you program in C, but do you write computer programs or applications?". I'm pretty sure this nuance mattered in the mainframe-era, but 15 year-old me did not get it at all, and frankly, I'm still not sure what he meant, despite doing it for a living. But nowadays the distinction disappeared (did the two merge? did one fade?), and the REST APIs nuances did also disappear to only keep the parts that matter: those that made this model successful.
