Well, a "properly prepared" Watson wouldn't be Watson any more. The games Jeopardy, Wheel of Fortune, and The Price is Right have little in common in terms of the type of algorithm and program needed. Jeopardy is about looking up relatively common factual information, Wheel of Fortune is about guessing phrases, and The Price is Right is about estimating prices -- all worlds apart when it comes to which algorithms would be used.
I suppose the point is that even our most "intelligent" programs and computers are still programmed to be good at one, and only one, task. It can perhaps be reprogrammed to perform a slightly different but almost identical task, but you can't use a program that is designed for one task and expect it to perform reasonably at some quite different task. Different tasks require different algorithms and sometimes even different specialized hardware.
They didn't say "if you get a scrape you will die." They said "if you get a scrape you could potentially die," which is a factual statement if we have no effective antibiotics.
This is a common strawman argument. Restate a scientists' position so that it is extreme, then chide the scientists for taking such an extreme position. It seems to be remarkably effective with a significant percentage of the population, but it seems transparent enough to me.
They just want money, so they say there will be some sort of catastrophe so they can get funding for their so-called studies. They even managed to throw in think of the children on top of their other hyperbole. I, for one, want absolute iron-clad proof that something disastrous will happen before we lift a finger to prevent it.
The above post may contain toxic doses of sarcasm.
