Well, I get the concern. Our platform keeps a business process graph in an actual rule-based language and enforces that graph continuously (literally 24/7). Some of the process steps in that graph can be executed in proper Python --in parallel, on the cloud, for TBs of data-- and some can even be executed in Excel (locally, for specified and controlled scope, hopefully for MBs of data). Excel is in the picture but in a controlled sandbox that can be avoided/automated away when the business team is ready.
