Likely you don't care because you have no intention of pursuing mathematics in a research capacity at any point. However part of the experience for those who care more about math than an easy "A" is ensuring you have access to amazing role models early on. People who take an interest in you, and spend some of their incredibly valuable time shepherding you through a unique, beautiful field.

Where is your sense of wonder, or your desire to know these exceptional people while observing how they think? How myopic. If you're at Berkeley, you're wasting your time being bitter and hopefully you'll transfer. That isn't a personal criticism, so much as recognizing that a top research university isn't for everyone, and the unique resources and access it provides should be given great weight or you shouldn't be using them.

Professor Ogus cared, as did almost all of my professors. I was amazed I could take classes and spend time with people who are shaping our understanding of mathematics. It's the same shock you have when you go to the SFMoMA and realize that some of the greatest post-Impressionist works in the world are sitting entirely unprotected in front of you. It impacted me, it impacted the way I think, and I will always value what they did for me. An adjunct simply can't provide that experience, and if you're just looking to pass Math 1A go to a community college for those credits. If you want to make a mark and know some of the brightest minds of our age, go to Berkeley.
