I think there is a valid point in this question, although the wording might lead to different interpretations.
I think @tomschlick hit it spot on with his reference to the first Laracon (I wan't there btw).
What happens with Laravel is something happens to Taylor (let's hope it does not happen, but still hypothetically). Does Taylor plan on keeping the framework alive for the next 5 or so years?
I mean it takes a lot of his time and resourse, and as we all know those are limited, does he feel he is going to be that dedicated for the next couple of years. We should not forget apart from pull requests and Laravel Elixer (at least to my knowledge) it is only Taylor who is doing the heavy lifting.
And I can see why people might wonder if there are 'contingencies' once Taylor stops beeing the engine behind Laravel (what ever reason that might be, he could for example just get sick and tired of maintaining it).
Again, don't take the question in the OP in the wrong way, the guy just wants to know how Laravel is organizationally structured and if it only hinges on Taylor.
