i'm trying to think of the coding equivalent of wooden wrenches? Let's say that's an app written entirely with VBA. If I perceive that it solves my problems, then for most use cases, i'd be fine with it. I guess if it's running my bank account or it's a platform for deploying my code, maybe i'd care somewhat, but in 99% of cases, i wouldn't.

But the reality is that most code is written in a language that's good enough. It's a metal wrench that might be showing some rust. Do I think that PHP is a good language to start a project with today? Of course not. Do I care if you wrote your site 15 years ago and it still runs on PHP? Not really.
