I think you nailed the key insight here... The Matlab community maybe needed a really close alternative at the beginning, but we should really strive now for python-centric solutions (and/or Julia/R...). Matlab is a tremendously poor ecosystem. Not flexible at all in terms of libraries, slow, closed source and poorly designed as a language. You could just see what Python has achieved in the last years as a scientifical tool: awesome libraries, interfaces with web/mobile applications, tons of rich courses/tutorials. I hope it teaches other fields that open source can really be key in making tremendous progress.
