I remember seeing and hearing about Film Composer while a student at The Art Institute of Dallas. We had two Media Composer systems on the old pizza box Mac computer. I think After Effects was a young buck at the time. Back then storage was not cheap and not much either. Went to class then saw a film next door, we were next to the General Cinema which is now part of the school. Sadly the one by the mall was torn down a few years later, a relly nice theater. Those were the days. We also were shooting on S-VHS and Betacam SP, and had the linear editing system. Times have changed, so has the workflow.
Perhaps we might be critical of technology as a whole, not just software. Think back when the new Mac Pro came about. That along with companies being proprietary with their equipment and ones that have gone rental only. My two cents.
