It's true, I don't have any significant personal experience with 3D modeling or animation. I think my point stands, though: It took a LONG time for Blender to catch up (exceed?) the proprietary alternatives, and it's certainly not going to see widespread adoption in industry for a long time more, if ever.
And it took a long time for LibreOffice to match Excel. And for LMMS to match FL Studio's capacities. And for Linux distros to become as user-friendly as Windows. Corporation-side, sure, it'll most likely take the retirement/death of the Baby Boomers for that to change. But it's already changing in the public, though.
Yeah. You still DO have to find instrument samples (the base ones are, as expected, not that great), but the beat and synth parts are just as developed as FL's. Still a little bit harder to learn, and your result will sound a little bit midi-ish if you don't entirely know what you're doing, but I consider LMMS to be professional-grade now.
