This is simplified, but:

Say you have a billion dollars in cash. With rates at 0% and inflation at 2%, you might as well spend that cash by hiring some engineers and chasing a hit product. Or an OK product.

With rates at 5% or so and 2% inflation you can make decent money keeping your cash in a savings account paying 5% YoY. Unless you're sure you have a good idea, you might as well park the cash and skip out on all of that "hiring engineers" business, which may not result in a good product anyway.
