...not only could a computer detect the boulder, it could detect it and brake (or turn or otherwise avoid the danger) much quicker than a human...
...and how will this amazing computer be able to detect a boulder rolling down a hill? It could just as easily be a tumbleweed, or an ostrich. Now, if it's an ostrich running down the hill, on a potential collision course, a human would instantly know that a fence will keep that ostrich off the road - and the tumbleweed is just a pile of sticks. However, the intelligent, autonomous car - not so much. I've programmed plenty of autonomous vehicles (some that fly) - there's ALWAYS something you didn't anticipate.
Computers aren't intelligent, they only know what they've been "told."
Assisted (and eventually self) driving cars are a godsend for the aging population. There are so many older people who think they can still drive but really can't. People just don't realize how diminished their depth perception and reaction time get as they age.
Computers aren't intelligent, they only know what they've been "told."
Again, this is not how a computer like Watson operates.
"What color is Dorothy's shoes?"
That question requires knowledge but more importantly it requires intelligence to answer. Dorothy Hamill, Dorothy next door, Dorothy who? Most humans, at least those in the US can answer that. Watson most likely can answer that correctly. There is nothing in it's database that says Dorothy's shoes color = ruby red.
Edit
---------
One other thing, if Watson gets a question like that wrong it will adjust the logic. It also also "learns" .

By the logic displayed in the post you quoted the computer is not at fault, the human that entered the wrong information, or programmed it incorrectly, is.

For the most part yes, but how many times have we seen in our IT careers problems with computers where it's had a problem and we sit there, scratch our head and blame the problem on:
~ Sunspots
~ Tin whiskers
~ Ghosts from the 5th dimension
~ Stray photons
Of course that's how it operates, it doesn't pull information out of thin air - it has to be fed information first .
For someone who has claimed to have built autonomous robots I would expect that you would understand this more thoroughly. In a typical computer program you have a set of instructions and structured data.
$TheColorofDorothysShoes = 'Ruby red';
You can feed all the information like that you want to a computer and it will never be wrong unless the data it was given is wrong. However it can only know exactly what you tell it. The task of providing it with everything known to man and storing all that information individually is insurmountable.
The data in Watson's database is not structured at least in the typical sense of the example I gave. It contains things like the entire contents of Wikipedia, The Bible and numerous other references. It needs to determine what color the shoes are from that data, there is no line in it's code that tells it Dorothy's shoes are ruby red. It can even be wrong.
