Thanks, that's an idea that makes a certain sense. The counter point is that technical things get replaced quickly at times when something vastly superior arrives. We don't use cpm computers or apple IIs any more. I think saying sql has the lindy affect is a clever slam against it. We don't use system 360 assembler any more. X86 seemed to be certain to own the world, maybe arm or risc-v will usurp it.
