Are there any open source or widely available Go engines that are even remotely as strong as AlphaGo (which I think we can safely assume plays beyond the 9p level, i.e., at superhuman strength)? If the only seriously strong engine is completely tied down behind the closed doors of a company that has largely already moved on to other challenges, I think that's the issue right there -- or at least a large part of it.

I think the strongest commercial engines are Zen and CrazyStone. Zen has certainly become pro-strength on fairly modest hardware (it had an exciting BO3 against a Japanese 9-dan, which it lost 1-2), but the strong version isn't available to the public yet, I think. Interestingly, for the past 3 or 4 days there's been a mystery Go Bot playing on 2 servers calling itself "Master" which is currently about 50-0 (!) against professional opponents, many at the very highest level. Nobody knows its identity yet. It's stronger than the commercial engines, and its presence must be some sort of stunt or test by someone. http://lifein19x19.com/forum/viewtopic.php?f=10&t=13913 http://lifein19x19.com/forum/viewtopic.php?f=10&t=13913

  It's 58-0 now. They've been playing 10 games per day since December 29. Diagrams with moves at https://tieba.baidu.com/p/4922688212?pn=150& https://tieba.baidu.com/p/4922688212?pn=150& Google translate helps with the comments but they don't add much to the diagrams. They are playing fast games with 3 time periods of 30 seconds per move. It means that one can exceed the 30 seconds limit and move on to the next period. When the limit is exceeded in the last period the game is over. Fast games usually increase the chances of the stronger player if the difference is large. Edit: 59-0 just after I posted this.

  Now confirmed to be AlphaGo. https://twitter.com/demishassabis/status/816660463282954240 https://twitter.com/demishassabis/status/816660463282954240

I think the next strongest engine is Zen ( http://senseis.xmp.net/?ZenGoProgram http://senseis.xmp.net/?ZenGoProgram ) which plays at amateur 9 dan level. CrazyStone is strong too. Strongest open source engine is Pachi, which has achieved an amateur 4 dan ranking on the KGS go server. Fuego is almost as good.
