If you’re
one of those people who bought Bitcoin or another cryptocurrency near its peak
last fall, you’ve lost a lot of money. Is it any consolation to know that you
would have lost a similar amount if you had bought Tesla stock instead?
OK,
probably not. Still, Tesla stock’s plunge is an opportunity to talk about what
makes businesses successful in the information age. And in the end, Tesla and
Bitcoin may have more in common than you think.
It’s natural
to attribute Tesla’s recent decline — which is, to be sure, part of a general
fall in tech stocks, but an exceptionally steep example — to Elon Musk’s
purchase of Twitter and the reputational self-immolation that followed. Indeed,
given what we’ve seen of Musk’s behavior, I wouldn’t trust him to feed my cat,
let alone run a major corporation. Furthermore, Tesla sales have surely
depended at least in part on the perception that Musk himself is a cool guy.
Who, aside from MAGA types who probably wouldn’t have bought Teslas anyway,
sees him that way now?
On the
other hand, as someone who has spent much of his professional life in academia,
I’m familiar with the phenomenon of people who are genuinely brilliant in some
areas but utter fools in other domains. For all I know, Musk is or was a highly
effective leader at Tesla and SpaceX.
Even if
that’s the case, though, it’s hard to explain the huge valuation the market put
on Tesla before the drop, or even its current value. After all, to be that
valuable Tesla would have to generate huge profits, not just for a few years
but in a way that could be expected to continue for many years to come.
Now, some
technology companies have indeed been long-term moneymaking machines. Apple and
Microsoft still top the list of the most profitable U.S. corporations some four
decades after the rise of personal computers.
But we more
or less understand the durability of the dominance of Apple and Microsoft, and
it’s hard to see how Tesla could ever achieve something similar, no matter how
brilliant its leadership. Both Apple and Microsoft benefit from strong network
externalities — loosely speaking, everyone uses their products because everyone
else uses their products.
In the case
of Microsoft, the traditional story has been that businesses continued to buy
the company’s software, even when it was panned by many people in the tech
world, because it was what they were already set up to use: Products like Word
and Excel may not have been great, but everyone within a given company and in
others it did business with was set up to use them, had I.T. departments that
knew how to deal with them, and so on. These days Microsoft has a better
reputation than it used to, but as far as I can tell its market strength still
reflects comfort and corporate habit rather than a perception of excellence.
Apple’s
story is different in the details — more about individual users than
institutions, more about physical products than about software alone. And Apple
was widely considered cool, which I don’t think Microsoft ever was. But at an
economic level it’s similar. I can attest from personal experience that once
you’re in the iPhone/iPad/MacBook ecosystem, you won’t give up on its
convenience unless offered something a lot better.
Similar
stories can be told about a few other companies, such as Amazon, with its
distribution infrastructure.
The
question is: Where are the powerful network externalities in the electric
vehicle business?
Electric
cars may well be the future of personal transportation. In fact, they had
better be, since electrification of everything, powered by renewable energy, is
the only plausible way to avoid climate catastrophe. But it’s hard to see what
would give Tesla a long-term lock on the electric vehicle business.
I’m not
talking about how great Teslas are or aren’t right now; I’m not a car
enthusiast (I should have one of those bumper stickers that say, “My other car
is also junk”), so I can’t judge. But the lesson from Apple and Microsoft is
that to be extremely profitable in the long run a tech company needs to
establish a market position that holds up even when the time comes, as it
always does, that people aren’t all that excited about its products.
So what
would make that happen for Tesla? You could imagine a world in which dedicated
Tesla hookups were the only widely available charging stations, or in which
Teslas were the only electric cars mechanics knew how to fix. But with major
auto manufacturers moving into the electric vehicle business, the possibility
of such a world has already vanished. In fact, I’d argue that the Inflation
Reduction Act, with its strong incentives for electrification, will actually
hurt Tesla. Why? Because it will quickly make electric cars so common that
Teslas no longer seem special.
In short,
electric vehicle production just doesn’t look like a network externality
business. Actually, you know what does? Twitter, a platform many of us still
use because so many other people use it. But Twitter usage is apparently hard
to monetize, not to mention the fact that Musk appears set on finding out just
how much degradation of the user experience it will take to break its network
externalities and drive away the clientele.
Which
brings us back to the question of why Tesla was ever worth so much. The answer,
as best as I can tell, is that investors fell in love with a story line about a
brilliant, cool innovator, despite the absence of a good argument about how
this guy, even if he really was who he appeared to be, could found a long-lived
money machine.
And as I
said, there’s a parallel here with Bitcoin. Despite years of effort, nobody has
yet managed to find any serious use for cryptocurrency other than money
laundering. But prices nonetheless soared on the hype, and are still being
sustained by a hard-core group of true believers. Something similar surely
happened with Tesla, even though the company does actually make useful things.
I guess
we’ll eventually see what happens. But I definitely won’t trust Elon Musk with
my cat.
