According to Ted Nelson, in the 1987 commemorative edition of
Computer Lib/Dream Machines, because things such as parallel processing, distributed processing,
hardware capability-addressing based security, and hardware language support (e.g.,
LispMs and the like) were seen by the academic community as the ways forward, they by and large ignored the rise of microprocessors until the hobby community was well established and the commercial and home use of 'microcomputers' began to grow, causing most of them to be blind-sided by the actual big development of the day. I personally can recall the dismissive attitude which many academics - and businesspeople coming out of the IBM sphere of influence, where mainframes were always seen as the 'real' computers and PCs were regarded as overgrown terminals even by those producing them - had towards personal computers even into the 1990s.
Microcomputers didn't represent any sort of conceptual advance. They by and large reimplemented well-established concepts on smaller scales and just plain ignored many conceptual advances throughout the history of computing. Home electronics hobbyist projects had been around since the turn of the 19th-to-20th century, so they weren't new. One interpretation of the hobbyist computers / microcomputers is that the byproducts of industrial computing achieved some sort of critical mass of usefulness leading to greater marketability as opposed to any sort of genuine innovation being involved. The standard post-WWII model of not-just-basic research being carried out at universities and by the military only to be given away to cronies in the private sector applied to computing as it did for aviation, medicine, and really everything else e.g. the internet. There is now a moderate secondary design field in existence, but even as they are distinct designs, they typically represent technically inferior solutions involving well-established concepts specialised to smaller systems with a strict subset of the technical developments of the history of computing as opposed to any sort of originality. FibreChannel, InfiniBand, enough RAM to make 64-bit meaningful above physical addressing extensions for 32-bit, etc. are all beyond the reach of the "mainstream consumer" beyond just multi-socket boards, or, for that matter, multi-board systems, or meaningfully powerful non-x86/RISC systems. So colour me disgusted regarding how technically inferior products are foisted on the mass market instead of best-of-breed designs and implementations actually trickling down.
