Is Devin really a full autonomous engineer?
It's the closest thing on the market. Devin takes a ticket, reads the codebase, plans, writes code, runs tests, iterates, and opens a PR. It's not perfect — you still need senior review for anything non-trivial, and it can burn hours on the wrong approach if the ticket is underspecified. But for well-scoped tickets in a codebase it's seen before, Devin genuinely ships PRs engineers merge. Tycoon's AI CTO is capable for simpler engineering (MVPs, landing pages, backend scaffolding) but doesn't match Devin on production codebase work.
