This paper isn't great. Yes, I can use a custom in-memory data structure, write it in Go and cluster it using some nice Raft replication. It's not all that hard and it's much, much faster than Redis. (we do this at Stream for activity feeds and chat) For most apps doing this is totally impractical. If you're using PHP, Python, Node or Ruby for a small to large (anything that doesn't have 100 million plus users) the overhead of implementing the pattern the authors suggest is just too large. I think Redis will only keep on becoming more popular...
