Great but then you tie your growth to the support people headcount. Normally you would see enormous costs upfront for R&D and bringing the thing up, then marginal costs when adding capacity (the hardware, mostly)—if capacity is proportional to the number of humans looking after the system, you will soon hit a limit, and the cost won’t look good either.
