The work companies put into ETL is absolutely bizarre from a business standpoint. Say you want to build a new kind of hammer. Normally what you do is you pay a company for access to some facility that has forging process, and you put your effort into designing the hammer, working with the facility to get it forged the way you want, and selling it. Building ETL pipelines from scratch is like building an ire ore mining facility, building diggers, trucks, shipping containers, trains, boats, iron smelting and forging equipment, and warehouses, on top of designing and selling the hammer. People today are so brainwashed by the idea that they need to be writing software that they go to these extreme lengths to build everything from scratch, when they should almost always be paying somebody else to do most of it, and only spend time working on your business's actual problem. Building factories and logistics chains should not be a problem your business needs to solve if all you need to do is build and sell a hammer.
