Execution in the article is simply having faster tech operations. Execution in a startup context doesn't imply that - execution is how the business operates - strategy, operations, hiring, marketing, legal handling, product building - all of that. Has AI made that easier, yes. But not how this article is soley focusing on an important but a very less significant part of a startup operation or the success it might have. Startup (even only a tech based) is not only tech product building, its a business. And, that execution incoporates all the functions of a business, not only tech product building.

Okay but product development alone being faster is still pretty exciting.
