Totally agree. Ultimately the only test for your startup idea is market acceptance and resonance - and experience repeatedly shows that no amount of prior experience and knowledge helps in predicting correctly what the next big thing will be. After the fact, it is easy to look back and rationalize and attribute certain factors for all the big successes - but no matter how many times this happens, we always miss the next big thing. Market resonance is very hard to predict - since there are so many parameters for success.

The success of Airbnb and many others like it raises the interesting question - How many other billion dollar ideas, never got off the ground because investors thought they were awful ideas? We may never know. But it should give every entrepreneur something to think about and not be discouraged by rejections. Your idea does not need to be accepted by investors - only by the market! So if you really believe in your idea launch it and see if the market accepts it. If not tweak the parameters till it does. Build a minimum viable product and try to fail cheaply. If it works, investors will come running to you. A good way to look at it is that your startup is like an experiment and your product/service is the hypothesis you are testing. If it fails, your hypotheis is wrong - so change it and try again.
