Specially when the "old things" are over-represented by things like C/C++/Shell, Unix and not Pascal/ADA, HyperCard/DBase/FoxPro (your "low-code" from the past!), Amiga, BeOS, etc A LOT of the old things were ahead of the time and forgotten. Also, a lot are still in their infancy (I think RDBMs are still too immature!). Is likely that marrying that old things with (1, at most 2) new things is the way to go.
