To me it seems that there is a segment of the Bitcoin community that are actually fearful of Ethereum. They try to protect against this by making it their mission to FUD everything that has the mere whiff of Ethereum. An unfortunate side effect of this is an inability to acknowledge any benefits that might come from smart contracts - which is ironic, since one of the true Bitcoin OGs , Nick Szabo basically invented the smart contract concept.
To my mind, Bitcoin has nothing to fear from Ethereum... any more than Bitcoin has anything to fear from any of its other testnets. The only thing we have to fear is the mental stagnation that comes with throwing the baby out with the bath water. I am not willing to concede smart contracts to Ethereum. We invented them, they are ours.
There is no point in white being afraid of black and black being afraid of white. Bitcoin and Ethereum are common competing systems that develop at the expense of each other. Competition has always been and will always be the engine of trade and development of any systems. This is a pattern of life confirmed over the years.
