In this specific case, I would start by trying to come up with an idea for a solution to an existing problem instead of trying to build a solution looking for a problem. Trying to build just another Siri will be wasting your time because you're just one person competing with pretty much all the big tech companies, whereas if you try to build a useful tech for a specific use case and people like it, then you can build your platform on top of it. I've never seen any small startup succeed by trying to build an ambitious "platform" from scratch. Most successful platform companies started out as small application providers and went from there. Some people are encouraging you to do it because that's how you learn things, but I would rather make something people like AND learn something new at the same time, instead of spending the same amount of time working on something that will never see the light of the day.
