I've been around in IT for a long time. I remember when Apple was dead in the late 1990s. Gone forever! I remember when Windows was going to be gone because, well, EVERYONE would use Linux, and it would be FREE! I mean it is free, but I'm still waiting. Gimp would kill Adobe! Still waiting.
All of that and yes, the Blender comment was a non sequitur.
To be fair, I'd be annoyed if I had to (re)learn Blender, but hey, if it were a better piece of software to kill the moribund stranglehold Adobe has on my industry, that's great! But I'm not holding my breath, and a more likely contender at this point is Blackmagic.
Open-source software is great for lots of things; I've yet to see it be an effective answer for professional solutions, though.
