That runs out of steam eventually. Hence need a leader with Vision that is filling the pipeline for next few years. Unfortunately. Once the money does run out

That runs out of steam eventually. Hence need a leader with Vision that is filling the pipeline for next few years. Unfortunately. Once the money does run out, and they do get someone with Vision, then that Vision takes years to realize, so there would be a big slump in products/money where they could just collapse. Usually it is a competitor that comes up with the new vision. Maybe Apple is so big it just buys other people vision.
