50 years on, we’re living the reality first shown at the “Mother of All Demos” (arstechnica.com)

Sorry but Russians were already living in that reality at that time. Especially MIR-2 with light pen and all that shit of 1969. It had the weirdest symbolic programming language with its own character set. http://www.icfcst.kiev.ua/MUSEUM/GL_HALL2/COMPUTERS/MIRS.htm...
