Actually novel ideas are very rare and very valueable.
That said you can build a perfectly viable business with not a single original thought. I.E. a restaurant or a clone of another business.
I'd split execution mainly in two:
Building
Selling
Building, barring some possibly extremely hard technical challenges, is not as hard as people make it to be, and LLM are definitely a huge help but I would never call vibecoding an entire application "Building a production ready SaaS".
Selling or, to put it better Product/Market fit, is what's actually very very hard and where most ideas fail.
Tado is currently testing (and apparently fumbling the rollout, as some users are already locked out) of a new subscription of 1£ a month per household. Without paying for the subscription you will apparently lose all access to the app and its most basic features, such as room temperature control and scheduling.
