Im thinking more along the lines of changing off of qwerty to dvorak. Theres an initial barrier to usage, but thats fine, if it actually resulted in something (significantly) better. With dvorak, there are power user converts, despite whatever benefit being minimal. Your many mouse example fails in that learning it doesnt actually lead to significant benefit, so ofc it'll never see converts; but if it did, if it was actually better than the three button mouse, then the initialization cost is overriden by the long-term benefit, and it remains possible for it to succeed. My point is primarily about the initialization; if this tech's only substantial negative is that it has to be trained to function correctly, and its benefit is substantial, then there remains a path to success. That is, the training step (alone) does not necessarily kill the technology. I can't think of any good examples off the top of my head
