Here's a list of commercial jet airliners: https://en.wikipedia.org/wiki/List_of_jet_airliners https://en.wikipedia.org/wiki/List_of_jet_airliners . About 68 have been developed, by less than 30 companies, over 70 years. In the meantime, a junior programmer on my team just got an assignment (while I was on holiday) to add a feature to an old project she'd never worked on. The feature was described in three sentences, with a budget of "at most two days" as that is what the work was sold to the customer for. I mean, it's rather hubristic to compare ourselves to those industries, we're closer to the handyman you hire to create a new door in some wall without telling him where exactly, all that matters is that it's done fast.
