I agree with you partially.
Since a few days, I begin to understand Blender (I can’t work wit it for the moment), by launching the app 15 or 30 minutes a day. Things are coming to be understand.
I think Blender is developed to be more simple from 2.8 to next future versions under a year. We can see the evolution in alpha 2.9.
About Rhino, I don’t like the UI but I love Grasshopper. You can use Grasshopper with very minimal knowledge of Rhino. If you learn Grasshopper it is fantastic. There is about 1000 components in Grasshopper, but about 20 of them are used very often…
