Does AI coding actually become multiplayer? Shared Slack agents vs. supercharged solo devs

A Reddit user with a psychology background, now working in finance/analytics, sparked a thoughtful debate after an MCP Apps meetup: is AI coding becoming genuinely multiplayer, or just making single-player developers more powerful?

Key points from the post:

One speaker does nearly all his coding through Slack, and Slack pushed the "AI coding in Slack makes development multiplayer" idea at Dreamforce — prompts, agents, decisions and outputs live in a shared team space instead of one dev disappearing into an IDE.
Another developer works heavily via voice. Technically voice and text both reduce to tokens, but for humans they aren't equivalent.
If everyone has their own AI agent, you may get extremely powerful individuals who still coordinate afterward. A voice-capable AI that follows multiple humans refining ideas live, maintains shared context, edits code mid-conversation and surfaces problems would look more like "Humans + AI → shared problem representation → collaborative output."
There's a hidden attention problem: Linda Stone's "continuous partial attention" suggests five devs each supervising multiple agents could be a nightmare, while a shared agent might let machines handle peripheral execution as humans keep joint attention.

The author asks what a genuinely multiplayer AI dev environment looks like, and whether voice actually changes collaboration dynamics versus shared text environments.
