China, being a planned economy at heart, has a "VC" system that is essentially just the government deciding what needs to be developed, and then Chinese banks lending without any practical strings to those developers.

Profit and loss, ROI, business plan, aren't really factored in. China wants to develop AI? You have some experience and want to start an AI business? Great! Here is a few million go make AI.

This is the system that led to those infamous ghost cities and billion dollar high speed trains to nowhere. China puts the carts before the horse, and hopes at at least a few of them get to the destination. They're not unfamiliar with burning tens of billions to get a few hundred million of value.

It also means that if you are competing against one of these chosen industries, you are not competing, because they are just burning daddies money, whereas you need to make interest payments.

Can't tell if this post is against VC system or just China?

Is that like TERCOM but using strength of gravity rather than terrain height?

Yup, I was just about to comment the same. I find it shocking that there's enough information/variation in gravitational field that you can match on.

What about weather conditions? Clouds, heavy rain, hurricanes, etc.

Not sure about weather conditions. What about magma flows?

Are there any good resources on how does one obtain all of this information?

I thought the same, but... I don't think it will ever go down. Stock prices are already divested from the company fundamentals, but they can only get so high, so the next _logical_ step would be to create something entirely divested from the stock prices itself. Enter tokenized stock.

> As introduced in the previous chapters, all identifers are hashed, thus we can also hash the known keywords at startup and make comparing them very fast.

One trick that postgres uses [1][2] is perfect hashing [3]. Since you know in advance what your keywords are, you can design such hashing functions that for each w(i) in list of i keywords W, h(w(i)) = i. It essentially means no collisions and it's O(i) for the memory requirement.
