Calculate how many nodes are needed for just 20 plies. Then you will quickly see that any program which can make 20 plies is not examining all the nodes. That will be true for any program which manages the feat this century. Hence, they will all be doing some kind of pruning. Therefore, there will always be loopholes in the algorithms used to exploit. sqrt(pow(35, 60)) is still a "rather large number" and I would not worry about any programs coughing up 60 accurate plies any time soon.
