Venture firm a16z just announced that it will be "moving its headquarters to the cloud." At the same time, it announced 3 new offices in Miami Beach, New York, and Santa Monica. These will be in addition to their existing offices in Menlo Park and San Francisco.

Part of their argument is that hybrid work is weakening the network effects and agglomeration economies associated with being right in Silicon Valley. So they've deiced to be virtual, but still have offices where they can "materialize physically" when needed.

They acknowledge that physical presence is important for developing a company's culture, building relationships, and helping entrepreneurs (their core business).

What's interesting about all of this is that it's further validation for Miami (Beach). Here is one of the most important venture firms out there saying that when they quickly materialize in real life, they want to be able to do that in Miami Beach.

It also raises some interesting questions. Because even if the network effects of Silicon Valley are weakening when it comes to tech, this announcement still speaks to the importance of agglomeration economies. These three new office locations were chosen for a reason.

This week, Lyft announced that it is going to be selling its autonomous vehicle division to Toyota for some $550 million. (Apparently $200 million of this will be paid upfront, with the remaining $350 million paid out over a five year period.) This is notable because Uber did the exact same thing last year when it sold its autonomous vehicle business to Aurora (which happens to be working with Toyota), and because the reasons for selling seem clear: getting to full autonomy is going to cost a bunch more money and both Uber and Lyft are determined to reach profitability sooner rather than later.

The other thing that you might be able to glean from these announcements is that neither company seemingly feels like they need to fully own/control the autonomous piece. Presumably the thinking is that someone else can spend the money on developing full autonomy and they'll just stick to building out their ride-hailing network. Once we have autonomous taxis, they'll need a network to run on anyway, right? I guess. But wouldn't this dramatically undermine the network effects of Uber and Lyft?

If you go back to Uber's S-1, there was a diagram that explained Uber's "liquidity network effect." See above. It starts with more drivers and more supply (1), because more cars driving around means that wait times and fares are lower (2) and so more people are likely to use Uber (3). Network size matters. But if you no longer have drivers -- only autonomous vehicles -- isn't it relatively easy to add more supply to any network? I suppose this partially depends on how the ownership structure will end up working for these autonomous taxis. Still, I wonder about the barriers to entry under this scenario.

Bill Gurley – who by the way is an investor in Uber – has an interesting piece up on his blog about the thing he loves most about Uber. It is the ability for the network to level load on its own. And here’s what he means by that:

In spite of all the ink that journalists, analysts, and pundits have spilled on Uber over the years, no mainstream article has focused on what I consider to be the most elegant feature of this now ubiquitous, high growth global service — no driver-partner is ever told where or when to work. This is quite remarkable — an entire global network miraculously “level loads” on its own. Driver-partners unilaterally decide when they want to work and where they want to work. The flip side is also true — they have unlimited freedom to choose when they do NOT want to work. Despite the complete lack of a “driver-partner schedule” this system delivers pick-up times that are less than 5 minutes (in most US cities (with populations over 25K) and in 412 cities in 55 other countries. The Uber network, along with Mr. Smith’s invisible hand, is able to elegantly match supply and demand, without the “schedules” and “shifts” that are the norm in most every other industry.

When surveyed, most people seem to prefer a job where they set their own schedule and get to be their own boss, compared to a steady 9 to 5 job with benefits and a fixed salary. Assuming that’s true, then this is a feature worth talking about.
