Back to the Future
This harks back to the old "mini-computers" of the 1980's. Unlike mass-marketed PC's, which had to be cheap to manufacture, the "mini's" had what were called backplanes, into which technicians inserted boards to accomplish the different functions of the machine as a whole. I remember being horrified when I first saw the guts of an IBM PC, where the peripheral boards were mounted onto the motherboard. Horrors!- I thought. This unstable situation will never last, the motherboards will crack after a few day's use.
Well, the idea has lasted thirty years so far. I wonder if this new possible modality will stave off early obsolescence, if adapted?
