> Basically ideas are a dime a dozen.

There's a spectrum of ideas, from groundbreaking to "dime a dozen". In tech startups, and in almost all of computer science, most ideas are a dime a dozen, and the value is in the execution.

But clearly, some ideas are groundbreaking. Einstein rightfully gets the credit for an on-paper hypothesis that wasn't proved until decades later via a chain of critical discoveries and experimental innovations by other people. It's legit to call it Einstin's relativity, and not Mossbauer/Hay's relativity.
