Baszucki: 20-Year-Old Roblox Deck Predicted Category of Human Co-Existence
“So there is a Roblox business plan PowerPoint deck from almost 20 years ago that we pull out sometimes and we're amazed at the fidelity of it. It pretends a new category. One could call it the category of human co-existence. It's got the sizes of a bunch of co…”
Baszucki: AI Worlds Will Span Shared Holodecks to Solo Real-Time Dreaming
“And so if you put those at two extremes, one is communication platform, high fidelity with people, you know, the other is real time dreaming where everyone's an NPC. Everything in between is possible. And I think we see everything in between ultimately as bein…”
Baszucki: Photorealistic 4D simulation will replace standard 2D video conferencing
“I think as a technology for multiplayer, four D simulation gets better and more photo realistic. It's almost going to be like video is the down sampling. And it's like, if we were having this for the immersive communication, we'd say go to legacy analog mode a…”
Baszucki: Roblox is adding full acoustic simulation and echoes to physics engine
“We are just started talking about full acoustic simulation. I just tweeted about it. So actually, you know, approximate, you know, attenuation and all of this kind of things and echoes that's going to start happening on the physics simulator.”
Baszucki: Synchronizing state for 10,000 players will unravel in 5–10 years
“The technology for this, I think we're going to start unraveling it over the next five to 10 years is what's the most efficient way To synchronize the state of 10,000 people.”
Roblox will store its entire platform history as 3D vector data
“I will share that the format we're using part of the vision for us is to ultimately store the history Of everything on Roblox, and to store it, not raster like video, but store it vector, which means the ability to play back anything that's ever happened on Ro…”
Baszucki: Roblox is training native AI NPCs to navigate and play games
“What we are starting to train is NPCs based on a combination of all of the data we have in a privacy compliant way that are starting to navigate and starting to play games.”
Baszucki: AI NPC platforms must run inference via cloud rather than locally
“I think to make that happen, these platforms have to be very cloud connected platforms rather than running local to spin up inference on all of these things.”
Baszucki: AI slop will not take over game creation from humans
“I think, you know, I'm not to the point where I believe, you know, what we call AI slop today is going to take over. Like, I think the human touch is Got a long runway on it.”
Baszucki: Five-person teams will produce astounding game quality with AI
“So, but I do think the role will be more leveraged and the quality coming out of five people will be astounding, you know, but we'll come to expect that quality. So quality will go up.”
Baszucki: World-model game architectures will not be all-in-one models
“And I think that the way we would see the ultimate architectures of these platforms is Probably for a while, not an all in one thing. We would probably see some hyper efficient thousand person synchronization state engine.”
Baszucki: Zero percent of today's children will have serious AI relationships
“I think zero right now. I do. I don't think we're close to crossing the human AI barrier.”
Baszucki: Cheaper asset creation is matched by rising consumer quality expectations
“One could say no matter how cheap it is to create assets, the expectation of quality from consumers goes up at exactly the same velocity.”
Baszucki: Gaming tech must move to vertically integrated cloud architecture
“That the technology for the gaming industry has to move to cloud vertically integrated and asset management can't just ship on a DVD or be a giant download.”
Baszucki: Top Roblox Creators Make $30M+ Annually
“The top Roblox creators now are well into the tens and tens and thirties plus million a year. Like it's really serious stuff.”
Baszucki: Roblox's 1,000th creator's earnings are growing faster than top earners
“We have seen in the Roblox creator community, I think a healthy sign that creator number 1000 and what is their average yearly revenue is going up faster than creator number one. So that's a bit of a healthy long tail.”
Roblox targets capturing 10% of global gaming content and 300M DAUs
“So we took a step, a stepping stone and said, we want to get to 10% of global gaming content. On the way to that. It's actually a remarkably good step. It's about three hundred million DAUs. It's about twenty billion. It's about three X where we are.”
Baszucki: Software CEOs must maintain both 3X and 10X targets
“I think for a software CEO, Always knowing both three X and 10 X is very helpful, because if you don't know 10 X, then it's hard to sleep at night. If you don't know three X, it's hard to plan forensically how we're going to operationalize that, how quickly we…”
Baszucki: Roblox ignores university pedigree as top talent bypasses elite schools
“Well, I think people typically think like I went to Stanford. That's where all the top talent is. We have found that not necessarily to be true. And we have found community college, you know, the small Midwestern engineering school, like, because we're assessi…”
