You would need smart contracts (then yes a proposal to do this could be fully automated), maybe we will have that, maybe not. There could also be multiple proposals run by different people doing the same thing, so it doesn't have to be me or anyone as a single point of failure. In theory if the market is mature enough you might not need the bot at all because people would do it on their own. If you can buy HBD for 95c you can make a profit. This then drives up the price of HBD. We just don't have a lot of attention to this chain nor a lot of capital involved with trading it. The stabilizer bot is serving to help bootstrap it, I think, but would stop being profitable and could go away at some point we enough other trading activity.
