Is there even a product to sell to medical? I thought Watson was just a proof-of-concept system. An actual product based on Watson would need to have some defined scope (i.e. only used for cancer treatments), would need some sort of FDA clearance which would probably require clinical trials. Is it there yet? Does IBM even want to take on the liability and expense of bringing it to medical? And is the market even big enough to interest IBM? Today, the "decision-support system" market is tiny.
