It is not a mistake.
"Effect.AI really enjoyed hearing from Steemit users last time. Since the topic of AI was of such huge interest, Effect.AI has sponsored another Steemit writing contest! This contest will revolve around their coming release of Phase 1: Effect Force (Decentralized Mechanical Turk)!"
This time we are concentrating on the release of "Phase 1: Effect Force".
Good question though, in case anyone else is confused. Upvoted for visibility.
Phase 1: Effect Force: This is the decentralized mechanical turk component. You can read about it more in the old contest linked above by @ulqu3 as well as in the post. Feel free to also ask them more about it on their Telegram!
Alright. Thanks for confirming.
