This originally formed from my interest in older computers. Early on, I wasn't as... versed as I am now, and I was generally distrustful of any technologies which strayed very far from the status quo formula we have been using for decades (CPU, RAM, HDD, Video Card, Sound Card, Etc.).
For me, making chips like that into a primary storage medium made no sense. I was also referencing ancient reports, back when SSDs were unstable- of course, that has improved greatly. I was of the thought process that we had perfected HDDs over the course of decades, and we had not yet done that with SSDs. I felt that they were glorified flash drives being adapted to be used as HDDs, and it seemed like a bad idea to me in general.
