I was expecting a data driven argument but the bits of data shared actually contradict the author. These companies mentioned are collectively worth $500B, after taking $100B in venture capital. They are starting to get profitable. Demand for their services is increasing. This article is thousands of words of the exact same talking points we have been hearing for a decade. What's the "after all" part?
I don't know what you are basing this on but it's definitely not based on data.
$UBER EPS over the last few quarters:
-1.28 0.61 -0.06 -0.54 -0.62
$DASH EPS
-0.30 -0.34 -2.67
The only way they are getting profitable is on an "adjusted basis", in other words when they exclude most of their expenses. That's not a business, that's a game.
