9:26 AM | For investors, all money isn't created equal
In our most recent discussion of driverless cars, I made the following assertion about Google:Google has a lot of reasons to want to be seen as a diversified, broadly innovative technology company, rather than as a very good one-trick pony cashing in on a monopoly (possibly two monopolies depending on how you want to count YouTube). A shiny reputation helps to keep stock prices high and regulators at bay.I didn't really think of it at the time, but this concern is a point we have hit […]
