A co-creator of AlphaGo, the landmark AI program from Google DeepMind, is the latest prominent researcher from the company to depart and seek significant funding for a new startup, according to people familiar with the matter.

Halo co-creator Marcus Lehto says leaving PvP multiplayer out of Halo: Campaign Evolved was a mistake. Lehto, who was the original art director for Halo: Combat Evolved, said split-screen multiplayer should have been included and mocked the decision on “lack of oversight and poor planning.” “Split screen MP in Campaign Evolved should have been included. There’s little excuse aside from lack of oversight and poor planning that led to this misstep. So sad this wasn’t included.” He later clarified that he was specifically talking about the remake not having PvP. “So sad this wasn’t included,” adding that it would be “awesome” if PvP were eventually added.

Fallout co-creator Tim Cain has seen a big change in how many people play video games today. Many gamers no longer make up their own minds by playing the games or reading regular reviews and instead let influencers tell them what to think. “Many gamers don’t even look to influencers for reviews; they look to influencers to be told how to think about the games,” “So people don’t form opinions from the online video; they’re handed an opinion from the online channel they’re watching.” He added that more and more people give up their own judgment, like “I don’t want to think about it. You tell me what I should think about it.” Cain has returned to full-time game work at Obsidian Entertainment. He said this influencer culture now shapes how games are made

Path of Exile co-creator Chris Wilson says developers have tried some pretty funny ways to deal with dataminers. One method was adding fake game files to confuse dataminers, Wilson says he tried this himself while working on Path of Exile. But in the end, he says it was a “pretty wasteful process” because devs were spending time making fake stuff instead of working on the actual game. Still, he admits it was “very good” for trolling. Wilson also explains that completely stopping datamining is extremely difficult. Encryption can help before a game is released, but once players have the game, the files have to be accessible for it to work.

Marginal Revolution co-creator @atabarrok says that AI replacing all jobs (which he doesn't think will happen) is a rich man's problem. "People are worried AI is going to do all the jobs. But this means we are going to be fabulously wealthy." "Even without any jobs, just being fabulously wealthy — we'll figure things out. This is the sort of problem you want to have." "This is not like a natural disaster, which destroys wealth. This is a tsunami which creates wealth." "Yes, it could be a tsunami in the sense that it's going to be very dramatic. But it's going to be very dramatic in the sense of like, Santa Claus coming and leaving us stuff under the Christmas tree. That's drama we can handle." "It won't be without problems. But problems where the pie gets bigger are problems we can solve." "It's problems when the pie gets smaller, when we are forced into a zero-sum society of one person versus another, that's when society breaks down." "But not when the pie is getting bigger. We'll figure out ways to make sure everyone gets a decent slice. We can solve the problem of dividing it up with everybody being happy. I'm much less worried about that." From his appearance on the show in May.
