I would speculate that innovation in this domain effectively stopped when the complexity of computer applications surpassed what the layperson was willing or able to wrap their head around. This happened some time just after the spreadsheet. At this point, businesses became highly dependent on skilled IT staff to hand-hold them through everything. IT staff are expensive, scarce and difficult to work with. They are also utterly preoccupied with rejiggering old ideas to work with flashy new technology, devoting very little time to truly new ideas. The problem concerns all of computing, both home and office. A vast knowledge gap leaves most people helpless while the experts are buried in architectural cruft, and often unaware of it.
