Self absorbed folks and VCs often ask this exact question, "why are you the only one with this idea?" which is short sighted and impossible to answer.

Either everyone else is stupid, or too lazy to come up with a plan to do it, or a myriad of other reasons. It doesn't matter why.

Like someone else pointed out the industry timing, state of technology and funding for that matter all drive these possibilities.

In the end only execution matters, and that comes with a long list of prerequisites aligning just right to even begin to form a possible positive outcome. It's luck and determination. The rest fail anywhere in-between, only to try again a decade or so later when the cycle repeats.

Welcome to the status quo. Don't like it?

Change it.

It matters because sometimes the answer is "others have tried this and it didn't work". What they want to know is that you've done your homework.
