Fun writing, and something to think about. To me, Web 2.0 is kind of a joke; jQuery, REST, AJAX, CSS2, RSS, single page apps were going to change everything overnight, it was THE buzzword, and then... incremental improvements. In retrospect, everything did change, but that loose collection of technologies was just links in the chain of incremental progress. So yeah, Web 2.0 2.0 makes sense. I've seen a lot of talk around here, and everywhere, about MCP. A lot of enthusiasm and a lot of criticism. I've written a few MCP servers and plan to write some more. It isn't how I would design a protocol, but it works, and everyone is using it, so hooray for interoperability. I think the hype represents the wider enthusiasm that people have about this moment in time, and the transformative power of these new tools. It's easy to look at MCP and say there it is, now it's easy to connect these tools to the things that I care about, it feels accessible, and there's community. MCP is NOT the new TCP for AI. It is, essentially, an RPC layer for chat. And while it could be extended to a wider variety of use cases, I expect that it will remain primarily a method for wiring up tool calls for user-facing use cases. We recognize the power of these tools and anticipate deep changes to workflows and systems, but we don't know how that will shake out. If I am writing a classifier for a backend system, I am not going to use MCP, even if I could. Because it's inefficient. Every additional tool we offer the model consumes tokens and increases latency. I expect that the primary user of LLMs is going to be business automation of all kinds, and I don't expect them to reach for MCP to wire things up. Yeah, it's really cool to hook tools up to the chat, for that to feel accessible, to know how to do things in an idiomatic and standards-compliant way, that feels good! And yeah, the hype is overblown.
