Which sequence describes a realistic succession of parental influences in invention?

Play leads to an unproven concept, doubt challenges it, necessity provides funding/focus, and desperation forces the final elegant fix.

A realistic model for significant invention involves multiple influences acting sequentially. The process often begins with playful, low-stakes exploration yielding an unproven concept. Established experts then apply doubt, scrutinizing the idea. If a market need arises, necessity provides the practical context and resources for viability. Finally, if the solution struggles under practical application, desperation might force the inventor to create the definitive, most elegant fix using insights gleaned from the earlier stages.
