   I am not memeber of Quora web site, but I saw this post   
   on it which has most upvotes on the topic   
      
   https://www.quora.com/What-is-the-difference-between-maple-and-mathematica   
      
   "Note that Sage is unlikely to be that competitor: its   
   fundamental design carries along the same flaws that Maple   
   and Mathematica have; most of those flaws were actually already   
   present in Macsyma years earlier, but the `conventional wisdom'   
   had not moved on to recognize these fundamental design flaws"   
      
   Unfortunately the post does not say what these fundamental design   
   flaws are. it is an old post from 6 years ago.   
      
   I wonder if any one would venture to guess or comment on what   
   these flaws might be? I am just curious to learn.
