What can you expect from a man who is 24 years old? He has zero experience dealing with customers.
I expect 6 - 18 year olds in my school to be responsible human beings that look after their peers. Why can't an adult do the same?
Age has nothing to do with this it has everything to do with basic ethical and moral standards that he and many of these companies lack when dealing with their investors / customers. Rather than working with the community and sharing relevant information like where are the chips and when they are going to be delivered all we get are excuses. Excuses are not what the community wants. We want information. Without information it is hard to make an informed decision on such tight time sensitive projects. How hard is it to provide that information? I suspect a 7 or 8 year old can set up a timeline schedule and offer a reasonable amount of information about how long it will take to produce a project for presentation. I have seen kids that age do it many times over the past 20 years why is it so hard for Yifu or Josh to answer simple question and give honest answers?
Clearly they will never get their act together as that sort of flaw is systemic in their nature and that is why avoiding them and their respective companies is a good idea.
