Because different faces, or parties for that matter, tend to pursue similar policies?
Right! If we'd elected McCain instead of Obama in 2008, the Affordable Care Act as we know it today would still be more or less intact, we'd still have withdrawn American forces from Iraq on the same schedule, and we'd still be shaking hands with China over a miniature climate agreement. In smaller matters, the Keystone pipeline would still be in limbo (just because that's easier than killing it explicitly). Et cetera et cetera.
With all due disrespect to Uber's extant valuation projections, you've used airlines as an example. Besides the fact that people travel on the ground more than they travel through the air, airlines are notorious for having razor-thin margins, spotty track records of profitability and a tendency to go broke on short notice. Their capital stock is a double-edged sword. You may have heard a joke: "How do you become a millionaire in the airline industry? Well, you start out as a billionaire..."
The real questions about Uber are how big the new market they want to build actually is, and why some competitor won't grab substantial portions of that market from them.
Why would it be different? I don't know, maybe because mammalian brains' learning mechanisms and the way they react to stimuli are shaped by a series of useful heuristics that arise from the bio-chemical structure of their brains, and it's not at all clear that there would be direct analogues in an artificial brain?
Whoa, whoa, slow down. I think you're a little off-base here. Be reasonable!
THAT's better than simply taking that money and investing it into the division?
I don't know, that could just be throwing good money after bad. This isn't a software division, it's not even like their server hardware division, it's chipmaking. It's kind of a go-big-or-go-home game where your competitors -- well-funded types like, say, Intel -- can easily pour many billions of dollars into next-generation fabrication processes and equipment which will readily put any half-assed investment to shame. I don't think IBM's chip business has the customer base to make "go big" profitable, or any reasonable plan to acquire new customers, so "go home" makes a lot of sense here.
Now, the wisdom / folly of gutting the rest of IBM's various divisions is left as an exercise to the reader.
Google feeds their employees dead cows and chickens on a regular basis. They should have used plants. These days, quinoa is in common use in foodservice, as are beans and eggplants, and lentils could also have been easily used instead. Google should leave beef out of its activities altogether.
