Why does AI make building easy but deploying still hard?

Something I keep running into talking to non-technical founders: the AI tools (Lovable, Bolt, Replit, v0) have basically solved the build step. People with zero coding background are shipping real apps now.

But the moment they try to get it actually live and keep it stable, everything falls apart. Custom domains, env vars that work locally and break in production, integrations that die on the server, apps that go down with no logs to explain why.

It feels like the barrier didn't disappear, it just moved. Building got democratized, operating didn't.

I've been doing manual deployments for a few of these founders to learn where exactly they get stuck (deploygo.dev), and the failure points are weirdly consistent.

Curious if others here see the same thing. For those of you building or shipping AI-made apps, where does it actually break for you? Is deployment the real wall now, or is it something else downstream?
