This year's coding agents are good enough to make large-scale code migrations a solved problem. See Bun's 500K-line Zig-to-Rust rewrite. Now the bottleneck is what happens after you move the mountain of code. An agent may write a million lines and make the tests pass. 1/3

But what do you do after that? And how do you approach this if your test coverage is thin? Here's how we migrated lovable.dev (400 routes, 850K lines, 42M monthly visitors) from Next.js on Vercel to TanStack Start hosted on Lovable itself. 2/3

In 20+ years in the industry, I've never seen software development change as fast as it's changing today. Lovable is a cool place that lets you work at the cutting edge and find out what the future of software development looks like [1/2]

AI writes 90% of my production code now. Speedup: 3-4x for prototypes, but only 1.5x for prod. The bottleneck moved from writing code to reviewing it. You still have to read every line. Field notes from 6+ months of coding with agents: 1/x

On code review: It's the new bottleneck. Every agent gives you a week's worth of not-great code in hours. You have to review it all. Your team has to review it all. Stacked PRs, better PR hygiene, AI self-review all help. 3/x

Only brave and skilled designer+developer can win the battle against IE7/IE8 incompability. I hope one day that skills would become obsolete
