I’m not a business person, but they’re already at the “hundreds of thousands of servers” scale, what about the 41st data center be organizationally far more expensive than the first 40?
Simple example: Pizza delivery service. The company runs very well, customers are happy, demand increases. At some point the demand gets so high, that they need to buy a second car for deliveries and a second pizza oven.
They look at the numbers and see the risk of making less profit than before, if they expand. Especially if demand decreases at some point, instead of growing further. So they decide to just raise the prices, lower demand and make even more money without additional risk.
GP's point is this isn't the 2nd car, this is the 41st car. If they had 1 car it'd be a 2x increase. If they have 40 cars, the only way the 41st car would lead to a 2x increase is if that single car cost as much as 40 other cars.
That's what the post you're responding to was asking.
The real question is whether it's actually just the 41st car or if the demand is such that they'd have to go from 40 cars to 200 and then risk having the demand fall back off after they've already sign on to making 160 more car payments.
For the 41st car they might need to build a new parking deck. Or hire a fleet manager, because the COO can't handle it anymore. They might already run over planned capacity and every new vehicle makes it exponentially worse.
For bigger orgs the bottlenecks are a bit more vague, but they still exist.
Do we actually know that? If you're an AI company during a hardware supply crunch and Hetzner has a bunch of servers they could put GPUs in and rent out to you, what makes you ignore them?
It's just not in their DNA. Hetzner is very much a do-one-thing-well business.
They might contract to AI companies to supply servers for their AI, but the total capacity of Hetzner is less than a single AI DC so it doesn't seem very useful.
It's a business that seems to have high operational leverage. Effectively, similar to airlines. Enormous capital outlays with low marginal costs, so once the current infra has been built at cost x, the additional data centre at cost 5x (or whatever multiple) might mean that it's not profitable to keep serving at the current prices.
Businesses charge their customers as much as they can. Businesses want to raise prices almost regardless of what their input costs are.
It is wrong to believe that a product's "correct" price is simply its cost plus a reasonable markup.
There's other factors that might limit how much a business can charge their customers. But an ideal business acts more like a monopoly and charges far far more than is 'fair'.
In theory competition keeps prices in check: in practice competition doesn't work as advertised.
Your overall point is true - but I'm unsure whether you are clarifying or trying to ackshualise.
And well actually, "price/demand elasticity curve" appears to be ambiguous word-salad (although a human mistake;)
I do appreciate your response: it makes me think about what I should have written. You are correct that my comment was rather unclear. Most of us misunderstand how businesses maximize profits. I find economics hard.
