Jeremy Morrell Argues LLMs Finally Make User-Written Extensions Economical, and Points at Salesforce Apex From 2007 as Proof
A 155-point, 67-comment HN post argues that most web software only serves the top of the demand curve because developer attention is scarce, and that LLM code generation removes the economics that kept the long tail unserved, so platforms should ship sandboxed user-authored extensions instead of more UI. The requirements he lists are concrete: fractions of a penny per run, millisecond cold starts, hard resource limits, fault isolation between users, and I/O granted through object capabilities rather than raw API keys. His note that Salesforce has run exactly this model since 2007 via Apex, nearly a decade before serverless, is the argument's strongest leg, and he names Cloudflare Dynamic Workers as the closest off-the-shelf option.
