I agree, but I think MSFT (and friends) are in this predicament no matter what. What's the alternative?
That said, I don't really think BRK is the end game.
For one thing, Berkshire is kind of an exception. There are plenty of smaller conglomerates that are actually like Berkshire, but most pretend not to be conglomerates. They pretend to be far more cohesive & synergetic than Berkshire.
Also, Alphabet shows that synergies can be easy to find. Youtube, Android... This generation's acquisitions need to be 10X bigger than that. But... these companies are in uncharted waters. No company has wielded free resources at the scale that MSFT now operates. They aren't the only one currently, but they don't have predecessors... unless we go back to VOC or somesuch.
OTOH... Satya is accidentally in the same position Buffet intentionally sought: Sitting on a pile of capital that must be allocated.
