Have seen those videos (quite good) and very familiar with the downfall of RCA, but not sure I agree with this take.
RCA basically set up an unworkable scenario and management did not heed the sunk cost fallacy to realize they were down the garden path. A stylus based cheaply made consumer electronic device with the technology at the time was pretty much impossible (and then of course by the time tech had advanced a stylus based system was totally moot). You could have hired manhattan project people and it wouldn’t have changed the physical/economic realities of what they were trying to do.
