I Blame Python

So MATLAB users are moving away from the language (and toolkit?) in
favour of other tools

Yes, proprietary languages and toolkits are a lot less attractive
these days, given the embarrassment of riches available in the
open-source world. MATLAB was probably good enough at the time for its
original use (matrix manipulation), but take advice from someone who
had to do programming work in that language (for pay, yet): *stay well
away* from the GUI-toolkit API, if you can help it.

It was a long time ago, but I still get the shakes thinking about it
