If we want adoption ahead of any competitors then the changes need to be made quickly or someone else will make them and be rewarded for the effort. This Brock Pierce guy TBF member came up with Realcoin because he sees a problem with Bitcoin adoption and wants a solution. I don't know if that's the right way to go but it's one way. Big business solves problems quickly because they have the money and resources to throw at problems. Big business and big money are becoming interested in Bitcoin. Will they decide to fix the problems or scrap the old and develop a new one? That's anyone's guess at this point.
It is pretty clear where businesses are primarily investing: Bitcoin. any businesses that decide to invest in Realcoin, stellar, or ripple will be investing in a protocol which lacks a critical feature which is driving adoption of Bitcoin: A steady store of value which cannot be manipulated directly by central planners or inflated. The flaw with Bitcoins volatility cited by Brock and Raison d'être of Realcoin is also Bitcoins strength. Initial volatility is necessary for the initial adoption and growth phase. If bitcoin was initially a stable unit of account during the formative years than their wouldn't be a massive investment to build and grow bitcoin as the early participants aren't incentivized as much.
