The Friendly Orange Glow is a history of PLATO – one that has long deserved to be told and that Dear does with meticulous care and detail. (The book was some three decades in the making.) But it’s also a history of why, following Sputnik, the US government came to fund educational computing. Its also – in between the lines, if you will – a history of why the locus of computing and educational computing specifically shifted to places like MIT, Xerox PARC, Stanford. The answer is not “because the technology was better” – not entirely. The answer has to do in part with funding – what changed when these educational computing efforts were no longer backed by federal money and part of Cold War era research but by venture capital. (Spoiler alert: it changes the timeline. It changes the culture. It changes the mission. It changes the technology.) And the answer has everything to do with power and ideology – with dogma.
