“We have found that in this new world where agents can end to end write much more code, reviewing the code is one of these new bottlenecks that, that crop up. And so reviewing a video is not a substitute for reviewing code, but it is an entry point that is much, much easier to start with than glancing at some giant diff.”

Nelle: Developers do not hand-code or edit files directly anymore
“People like don't really edit files, hand code anymore. And so we want to build for where that's going and not where it's been.”
Nelle: Coding workflows will shift from inspecting diffs to previewing video demos
“That's going to happen again, where it goes from agents handing you back gifts and you're sort of like in the weeds and giving it, you know, 32nd to three minute tasks to you're giving it, you know, three minute to 30 minute to three hour tasks and you're gett…”
Nelle: 10-Person Startups Using Cloud Agents Will Need Enterprise-Scale Dev Pipelines
“As with cloud agents, you scale up this parallelism and how much code you generate, 10 person startups become Need the DevEx and pipelines that a 10,000 person company used to need.”
Cursor removed web file editing to force users to delegate to agents
“And we actually felt that, that in some ways by restricting and limiting what you could do there, people would naturally leave more to the agent. And fall into this new pattern of delegating, which we thought was really valuable. And so there's currently no wa…”
Nelle: Optimistic AI compute buildout forecasts still underestimate agent demand
“Even with You know, the most optimistic projections for what we're going to need in terms of build out are underestimating the extent to which these swarm systems can like churn at scale to produce code that is valuable to the economy”
Nelle: Developers will spend thousands to tens of thousands monthly on agents
“I think as we think about these highly parallel kind of agents running off for a long time in their own VM system, We are already at that point where people will be spending thousands of dollars a month per, per human, and I think potentially tens of thousands…”
