Do guys like you think that the Bitcoin Core team is blind for these problems? Stating the obvious and being dramatic isn't helping, rather find out what Bitcoin Core is doing so far and if they stopped developing for Bitcoin. If they say: "We think Bitcoin right now is great and it doesn't need updates anymore" I would be the first one sending everything to Bitcoin Cash.
Like you I would have much more trust with a clear road map ahead for Bitcoin. But since there is so many parties with interests involved in how Bitcoin should progress, Bitcoin Core seems to reach out for stability first. Technology should always be changing and improving, but I have respect for their attempt of getting consensus before pushing new things. Compared to Bitcoin Cash they seem to me to be more professional and at least have way more experience. If they can keep these two things going at the same time, stability and change, this is the best that can happen to Bitcoin. Investors like stability, believers of Bitcoin as a currency like constant change and improvement to be technically superior to the old systems.
