$50 billion might be a stretch, but it's not far off.
Note: Cycle time is the amount of time it takes to produce a part. It's sort of like the MHz of the manufacturing world. Usually car plants are setup such that there are n manufacturing lines in operation at any given time producing/assembling parts. So you're always at the mercy of the slowest line. It takes months to comission a new line so it's not just a matter of "adding servers" to improve production.
