>> Compute is literally being sold as a commodity today, software is not.

The marginal cost of software is zero. You need some kind of perceived advantage to get people to pay for it. This isn't hard, as most people will pay a bit for big-name vs "free". That could change as more open source apps become popular by being awesome.

Marginal cost has nothing to do with it - you can buy and sell compute like you could corn and beef at scale. You can't buy and sell software like that. In fact I'm surprised we don't have futures markets for things like compute and object storage.
