This is a continuation of my last post,since today's top notch engines are still having gap with stockfish,do you think there will be a brand new engine to dethrone stockfish?
I would like to hear your thoughts.
Do you think a brand new engine will surpass Stockfish in the future?

Re: Do you think a brand new engine will surpass Stockfish in the future?
It's a badly worded poll question, because it doesn't specify a time limit. I think it is pretty certain that Stockfish won't be the best chess program fifty years from now, but it will probably still be the strongest six months from now. It also depends on whether the question is how well the programs play the initial position (or the most popular openings at top level), or how well they play from unbalanced positions as used in CCC and TCEC. Chess is indeed close to being "solved" in terms of being able to at least draw every game with good openings, but it is very far from solved in terms of being able to find the draw or the win in positions near the win/draw borderline.
Komodo rules!

If Mr. Larry Kaufman is still programming in 10 more years, if NOT it could be Berserk-16
Also, it depend on the starting position and time control
