There's still a lot of split screen games, Spelunky 2 comes to mind. Software features we've lost: (1) Shareware (2) Buying software as a physical experience: the box, the manual, the map, the 'keyboard overlay', the retail display, the retail shop, visiting with friends to see what's new. (3) Concise, locally available documentation (eg. man pages/CHM). (4) General software efficiency. Losses in related areas: (1) Common hardware platforms. (2) Upgradeable/maintainable hardware. (3) Areas of the house dedicated for computing. (4) Reading. People are not reading so much as before. This impacts negatively areas such as language development, vocabulary, grammatical complexity, and capacity for communicating and reasoning in structured/non-narrative formats. (5) English as a native language with native language comprehension, vocabulary and grammar levels. English is now a second (or third) to most of its speakers affects the depth and breadth of complexity that it is possible to utilize with most audiences. (6) General shift to short attention span, meme/viral optimized, consumption-oriented, online media experiences (Smart TVs, tiktok, youtube shorts, twitter, etc.) encouraging emotional/reactive/consumption experience rather than a wondrous/creative/concentrated/more well rounded experience of technology.
