If everything works as planed with Segwit, Bitcoin Cash will Crash.
Any net search will lead to Bitcoin.
Exactly. If Bitcoin Cash continues to decline in value over the exchanges, and provides poor innovation, then it will die soon. On the contrary, Bitcoin is the original chain and has managed to gather a wide audience, which has the longest standing reputation and support from its miners and node operators.
As of now, mining Bitcoin is more profitable than doing so with Bitcoin Cash, so miners will stay with the original chain, unless it becomes profitable to mine in the BCH chain.
Things aside, it's been a week since the launch of BCH, yet there hasn't been any innovation or active development. If it remains as is, then it will be just a pure speculative coin, and another altcoin which is cloned from Bitcoin's codebase.
The original Bitcoin chain will grow and survive for many years to come. Exciting things like SegWit, block size increase, and the Lightning Network, will greatly boost its adoption and make a positive effect in its price.
All that lies ahead is for SegWit2x to become fully complete (the block size increase part) and Bitcoin would've made a major milestone in history. Just my thoughts
