I think the SegWit solution is doomed to fail, but that could just be wishful thinking on my part.
I expect a strong push for SegWit as well as Cash. SegWit to crash Bitcoin so that Cash can become the new original Bitcoin raised from the ashes of the original Bitcoin like a phoenix.

However, I could be underestimating people's investment choices. Perhaps the SegWit chain is going to be inflated by whales dumping all their Bitcoin into it or blatant propaganda or exchange manipulation. However, there is a chance that this does not matter if most people keep their Bitcoin in the original version. The original Bitcoin can solve most of its immediate problems with larger blocks, though it may not be an ideal solution, it's a good solution for the short term (2 years or so). But of course even with a larger blocksize the system could still be abused without effective countermeasures. Nonetheless, I think that 2 years of time is enough to develop an adequate solution or some form of protection against abuse.
