I pitched in. There are a tonne of problems that are highly parallel in nature, but need a general purpose processor such as this. You can't just "run everything on a GPU instead" like everyone else is suggesting. Things like if statements are horrendous on GPUs. This gives you the power to scale across, without being limited to GPU architectures. It's also significantly cheaper in the long term than cloud hosting and uses significantly less power than clustering desktop PCs (which is also more expensive, and takes up more space).
