前幾天 Blizzard 公佈的消息，DeepMind 的星海爭霸二 AI (AlphaStar) 將會透過 Blizzard 的 Battle.net 歐洲區伺服器跟人類對戰：「DeepMind Research on Ladder」。
Experimental versions of DeepMind’s StarCraft II agent, AlphaStar, will soon play a small number of games on the competitive ladder in Europe as part of ongoing research into AI.
預設是不會對到的，需要選擇參與：
If you would like the chance to help DeepMind with its research by matching against AlphaStar, you can opt in by clicking the “opt-in” button on the in-game popup window. You can alter your opt-in selection at any time by using the “DeepMind opt-in” button on the 1v1 Versus menu.
但你仍然不會知道對手是人還是 AI，而且如同一般對戰情況，這會影響到你的戰績：
For scientific test purposes, DeepMind will be benchmarking AlphaStar’s performance by playing anonymously during a series of blind trial matches. This means the StarCraft community will not know which matches AlphaStar is playing, to help ensure that all games are played under the same conditions. AlphaStar plays with built-in restrictions that the DeepMind team has defined in consultation with pro players. A win or a loss against AlphaStar will affect your MMR as normal.
okay，這樣大概知道為什麼只開放歐洲區了...
加州從今年七月開始，禁止 AI 偽裝成人類 (前幾天也有一些新聞在報導)：「A California law now means chatbots have to disclose they’re not human」，對應的法條在「Bill Text - SB-1001 Bots: disclosure」這邊可以看到：
17941. (a) It shall be unlawful for any person to use a bot to communicate or interact with another person in California online, with the intent to mislead the other person about its artificial identity for the purpose of knowingly deceiving the person about the content of the communication in order to incentivize a purchase or sale of goods or services in a commercial transaction or to influence a vote in an election. A person using a bot shall not be liable under this section if the person discloses that it is a bot.
(b) The disclosure required by this section shall be clear, conspicuous, and reasonably designed to inform persons with whom the bot communicates or interacts that it is a bot.
而加州是 Blizzard Entertainment 的總部...
法條上面對「online platform」有設計排除條款，不過如果只算星海二的人數，有可能不到這個豁免限制... 所以得避開而改用歐洲區來測試？
(c) “Online platform” means any public-facing Internet Web site, Web application, or digital application, including a social network or publication, that has 10,000,000 or more unique monthly United States visitors or users for a majority of months during the preceding 12 months.
(c) This chapter does not impose a duty on service providers of online platforms, including, but not limited to, Web hosting and Internet service providers.
美國軍方應該是超級關注這個議題，相較於 AlphaGo 或是 AlphaZero 是資訊完全透明的遊戲，這次要踏入非對稱資訊的遊戲。
如果在這個領域上有成果的話，可以預期未來的戰爭 (yeah 實體戰爭) 會開始大量採用 AI 了...
