and earlier Simon Willison argued[1] that Skills are even bigger deal than MCP.
But I do not see as much hype for Skills as it was for MCP - it seems people are in the MCP "inertia" and having no time to shift to Skills.
I mean, MCP is hard to work with. But there's a very large set of things that we want a hardened interface to out there - if not MCP, it will be something very like it. In particular, MCP was probably overly complicated at the design phase to deal with the realities of streaming text / tokens back and forth live. That is, it chose not to abstract these realities in exchange for some nice features, and we got a lot of implementation complexity early.
To quote the Systems Bible, any working complex system is only the result of the growth of a working simple system -- MCP seems to me to be right on the edge of what you'd define as a "working simple system" -- but to the extent it's all torn down for something simpler, that thing will inevitably evolve to allow API specifications, API calls, and streaming interaction modes.
Anyway, I'm "neutral" on MCP, which is to say I don't love it. But I don't have a better system in mind, and crucially, because these models still need fine-tuning to deal properly with agent setups, I think it's likely here to stay.
I don't know, even ChatGPT 5.1 hallucinates API's that don't exist, though it's a step forward in that it also hallucinates the non existence of APIs that exist.
But I reckon that every time that humans have been able to improve their information processing in any way, the world has changed. Even if all we get is to have an LLM be right more times than it is wrong, the world will change again.
