This is something I used to believe.
I am a hobbyist user. Mathematica was not required for my work or for any other interests outside personal curiosity and an ever growing love of math and science.
I’ve made it an indispensable part of my work. A small side-project in Mathematica blossomed into one of the key ways my clients analyze data now.
Mathematica costs less than a dollar a day. It’s always open among the apps on my desktop on both my work Mac and my kitchen Mac.
To stop using Mathematica, you’d have to pry it away from my cold, dead hands. It’s really that great.
