Capitalism as a system has many impersonal qualities, but capitalism per se does not value anything. It just provides mechanism (market prices, investment dollars, and so on) by which the value that people attribute to things can be known.

If "capitalism" values the "wrong" things it's because people at large have the "wrong" values. If that is a problem, it's probably not an economic one, but something deeper.

Nope, capitalism as a system very much values particular outcomes. It's not a machine that perfecly translates human values into economic output; it's a system that actively prefers one type of values over other. The powerful feedback loops of markets that - I very much acknowledge this fact - led us to prosperity we enjoy today have a side effect that is increasingly becoming apparent: they slowly throw away any human value that stands in a way of being more competetive.

Anyway, that's a long topic. The TL;DR of my point is: it's not our values that control the system, it's the system that controls our values.

That this is actually a serious question shows that there is a strong mismatch between our values and the system we live in.

It values capital and the capitalist class, which is why it was named "capitalism" by its critics (specifically, its socialist critics.)

The free market justifications in terms of Econ 101 simplifications that, in addition to applying to a simplified version of reality in operational terms, also apply to a system different than capitalism as ever actually implemented, came later.

In this case I think the valuations are justifiable.

Imagine that all the people that sent a Whatsapp message in the last year were charged SMS rates for the messages they had sent. How much would that cost them? Well, that's a reasonable rough measure of the value they have derived from Whatsapp. It's an important service that has real immediate benefits for the people using it right now.

SpaceX is a fantsastic venture, I'm very excited by it, but right now it's providing limited economic benefit. The Space Station is an expensive waste of money. A few comms satelites is great, but there haven't been all that many of them. Now, if SpaceX does manage to recover and re-utilise it's boosters that willbe a game changer. Their value will skyrocket (appropriately) and Google will make a killing on their investment. But that hasn't happened yet.
