Number of new jobs for one. They just laid off ~300 people working on an older node in Lehi, Utah, while now claiming they’re going to bring new jobs to Lehi, Utah. Thus “new jobs” don’t really track the actual change in the number of their employees even just at the local level across even moderate timescales.

Similarly hyping up total R&D spending without a tight timeframe is meaningless, they will eventually spend X$ assuming the company survives indefinitely.

More charitably there’s meaningful differences between nodes, but it’s likely a significant portion of the workforce will be rehires.
