Nvidia's new financial strategy does not compute

Even if Nvidia hit a wall and can't outclass its old chips they still have a significant experation date on them since using them in data center situations destroys them over relatively short time frames for finance (a few years).

Note that for an asset class the fact that they can last longer isn't important, if they are fungible it means investors need to predictably know the lifespan which requires pessimistic usage assumptions.
