For me, they are very unreliable and dangerous questions. Mostly asked by people who are wasting months to validate thoughts and seek the next imaginary unicorn, that doesn't exist yet and has no competition. :)<p>You immediately assume that you need to have more expertise and be 10x better than the competition. But the business building doesn't work like this, in most circumstances, you'll start from something small, and then become an expert in it. Placing research and business decisions in the hands of customers who mostly say "no, we don't need this..." is just unreliable. Sometimes most stupid and simple ideas can change everything, which was proven many times.<p>Don't waste time and focus on building actual products, then validate, pivot, validate, pivot, validate, stay, earn millions, acquire more companies, get more money, build some more companies, finish with an empire... But try to avoid Walter White's fate. ;)
