I had a client simultaneously telling me he wanted a function, but that it couldn’t take that much time to develop it because it’s only useful 5% of the time. Sorry dude it’s all or nothing, it’s not like mechanics were there is a range of solutions going from sheet metal to forged titanium or from a piano hinge to magnetic bearings. I’m a bit unfair, because some high tech stuff is cheap, we all use tree and hash structures whose development we don’t pay because they are in the standard library, but it’s a few strategic and standardized places. The same as using a ball bearing in mechanics: you get into a very high tolerance world for cheap, the mechanical interface is standard and some unicorn mounted helve make those bearing in a chocolate factory as far as I know they might develop maps and queues on their other half time.
