“The failure mode of outsourcing the thinking, but not the typing, which I think it should be the opposite. You still have to know engineering. You still have to know how to program. You still have to know your application and its architecture, how it's deployed. And then basically use the agent to do the work that you would have done But you have to know what the desired outcome is and whatnot.”

Ball: AI coding tools must optimize harness and scaffolding per model
“And people are now also waking up to the fact that it's not just the model, it's the system prompt, it's the tools, it's the harness. The scaffolding around the model. So I can give you the choice to use Gemini 2.5 in, in AMP, but without the system prompting …”

Ball: Foundation models will become background implementation details in AI tools
“So I think we're going towards a future where the model will become an implementation detail to some sense, and we will end up on a different abstraction layer.”

Ball: Custom MCP tools fail if workflows diverge from frontier training
“If I give it this other custom-made MCP that we built internally, and our processes don't map to anything that OpenAI and Anthropic have seen or trained for, it won't be used, and you won't get good results.”

Ball: Developers are actively modifying codebases to suit AI agents
“What we're seeing now with agents is as soon as somebody has seen what it can do, they have such a multiplying effect or this brings so much value that people are willing to adopt the code base for this. Like the first time in how many decades where people are…”
