Sure. But it's not unusual for an invasive technology (that's us) to
take root in certain niches before spreading more widely.
Another way of looking at such things is: is what we are seeking to
replace that much worse? If the gains are marginal, then it is very
hard to displace. But if there are significant advantages, eventually
they will win through. I tend to think Python and the scientific stack
does offer the potential for great advantages over IDL or matlab. But
that doesn't make it easy.
