The hype cycle, the S curve, the diffusion curve, the Kano model, Moore's (Moo's) law - these (kinds of) models) all help anticipate how supply, demand and sentiment will evolve

At a high level they might help guide decision making, eg in capital allocation
That said, I wonder whether they will persuade anyone who isn't already somewhat bought in
