It's not a net neutral for most companies. It's a huge benefit for all the companies in that area. Skilled professionals have a choice of region and company to work in. IF they choose one with better terms for them, then that region will have a more skilled pool of workers. This benefits companies in that region. One could argue that the stronger ecosystem and pool of employees creates significant benefits that outweigh any corporate advantage due to restricting employee mobility. That's what the above reference is arguing.
Ok I'm guessing you're a new grad. If you're already working this might not apply.
Use this time to do things OTHER than work. Work out. Travel. Rest. Visit friends. spend time with family. Read for fun.
The other suggestions here are all good. very useful. It's just that this is a great opportunity to do things you can't do when working.

It's still pretty cool and could be very useful. That doesn't mean there aren't useful applications. It just means there are design tradeoffs.
Here's a nice article with pictures on sphere point picking[0]. Here is another [1]. The surface of a sphere in 3-dimensional space has only two dimensions. You can specify any point on the sphere with two coordinates (spherical coordinates). The mathematical expression for this sphere is S-2. If you're using three coordinates to generate the point, you're using more than you need. It's straight algebra to convert from spherical to linear coordinates if you need those for your work.
John McPhee write an excellent article about this: "The Ships of Port Revel" by John McPhee. It was an atlantic article and is included in his book "Uncommon Carriers".
