I'm glad you can.

Even before agents, I'm pulled to work on at least a couple different projects a year, the successful ones with teams of 10s of people working on them. If I stay longer than a couple of months, I eventually become the expert on some of the things I did, so I get pulled years later to review something I haven't touched in ages, which has changed requirements, and grown a bunch of dependents.

That was the reality of working on a team with hundreds of people and dozens of related products.

Now agents are helping people increase complexity and velocity N-fold.

You can call it a problem in the coal mine, but there's no going back. GitHub simply has no choice but to handle this new scale.
