Computer vs computer chess soon to an end?

[APassionForCriminalJustic]

Provocative question to provocative title: what is the point of running someone else's engine using your personal account in a public arena?

Running someone else's engines in a tournament, I understand.
Running your own engine in an on-line environment against other engines (or humans), I understand.
Being person 318182319 running some off-brand Stockfish in an on-line environment against other engines I don't get. What do you get out of it?

Anyway, the answer to your question is: that depends on what you want to get out of it. Computer chess, in a sense, has been dead since personal computers overtook human grand masters.

Enjoyment.
