The Downside of Asking AI Instead of Each Other

AI tools are making individual developers faster, and that's genuinely useful. But I've been noticing something shift on teams that I think is worth talking about. When you used to hit a problem you couldn't solve on your own, you'd ask someone. You'd drop into their DMs or post in a team channel. And in the process of getting your answer, something else would happen. You'd find out what they were working on, or learn about a related problem they'd already solved. You'd discover that two of you were heading toward the same part of the codebase from different directions. That incidental coordination was a side effect of asking for help, but it turned out to be doing a lot of quiet work. What happens when you stop asking AI tools are good enough now that a lot of questions that used to require a teammate can be answered independently. I'm not arguing against that. But the side effects are worth noticing. When folks stop asking each other for help, they stop discovering what each other are working on. Two engineers can independently solve similar problems and arrive at completely different approaches. Both solutions work. Neither composes with the other. Six months later, someone encounters both patterns in the codebase and has no idea which one to follow. I've seen this happen. The PR looks fine in isolation. The code is clean, the tests pass. But when you zoom out, the team has three different patterns for the same kind of problem, and nobody remembers when that diverged or why. What happens to trust There's something deeper going on too. The small interactions that build trust on a team (asking for help, working through a problem together) are the connective tissue of how teams actually function. The informal stuff. The moments where you learn how someone thinks and what they care about. AI doesn't replace those interactions. It just makes them less necessary in the short term. And the short term compounds. If you go three months without a reason to pair with someone, you don't just lose the pairing. You lose the relationship that pairing was building. I think a lot of what we call "team health" is actually the result of a lot of small collaborative moments. When those moments get quietly replaced by individual tool use, the team can feel fine for a while. But the foundation is eroding. I'm not sure what the answer is I don't have a clean solution for this. But I think we need to notice what's happening and be intentional about replacing the coordination that used to happen on its own. A few things I've been thinking about: Make work visible earlier. Not status updates after the fact, but lightweight signals about what folks are exploring. Async threads where someone says "I'm looking into how we handle X" before they've solved it. That gives others a chance to say "oh, I ran into that last week." Invest in shared learning spaces. Dedicated time where people learn together, not just independently. Book clubs, study groups, code walkthroughs. Not because the content requires it, but because the interaction does. Preserve the hallway. Whatever the equivalent of the hallway conversation is for your team, protect it. Maybe it's a weekly unstructured call. Maybe it's a Slack channel where people share what they're working on. The format matters less than having a space where accidental coordination can still happen. Keep code review human. I've seen teams start using AI for initial code review passes, and that might be fine for catching bugs. But a big part of code review's value is shared understanding. If nobody on the team is reading each other's code, you lose that. I keep coming back to the same observation. AI can make individuals faster, but speed without coordination creates drift. And drift is hard to diagnose because no single decision caused it. Things just slowly stop fitting together. I don't know if this is a temporary growing pain or a structural shift. But I keep seeing it, and I think it's worth asking whether others are seeing it too.
