You are obviously neither a CPA nor an MBA. The general rule of thumb is that an investment must have a ROI of less that 7 years max, and ideally under 3 years. Otherwise, you are much better off making a different investment choice with 8.5 Billion dolars.
That's why they are CPAs or MBAs, not school dropouts that created MS and Apple.
