Hot take: single-agent coding tools are the new FTP

Using one AI agent at a time in 2026 feels like deploying via FTP in 2015.

It works, but you're leaving 80% of the throughput on the table.

I've been running 5-12 agents in parallel for the past month. The productivity difference isn't incremental - it's a step change. One agent on auth, one on tests, one on docs, one on API endpoints. All at the same time.

The hard part isn't running them. It's coordinating them:

- Who merges first when two agents touch the same file?

- How do you stop an agent that's been looping for 20 minutes burning $4 in tokens?

- How do you review 200 lines of code from 5 agents before your coffee gets cold?

That's why I built [Bernstein] — an orchestrator that handles the coordination so you can focus on the goal, not the plumbing.

Curious - who here is already running multiple coding agents in parallel?
What's your setup? What breaks first?
