MCP everywhere is going to be such a societal changer. Once your bank and credit cards get MCP servers, that's it. It's next level society. Like, immediately, I want it to order me some groceries based on what it sees in my fridge and what I cook. And to remind me to change my air filters. Or book my vacation for me, knowing I like a mediterranean vibe and Bistecco Florentine. I am absolutely excited for all of this.…

For speeding up chores it can be useful but removing the actual fun part of experiences, the research, the looking into, the figuring out, to instead only get the result of it sounds like a quick path into unfulfilling experiences.

But to be honest, I don't think it will get to the state you dream about, just like smart homes never got close and are more of a hassle than an actual life improvement. Unless it is almost 100% perfect it will error out in ways that are extremely annoying, ordering the wrong groceries, booking the wrong trip, etc. It's really hard to cross over the point where it's absolutely helpful without hiccups.

Sometimes Go can get under my skin. The MCP SDK makes you jump through all these hoops to configure tools according to a JSON schema, but when it comes to handling the actual request you need to deal with parsing everything again out of a `map[string]any`. It's such a pain to need to reach for codegen all the time.

Go is pretty miserable for dealing with JSON compared to Python

It applies to most stuff not only dealing with JSON, but it got lucky being tied to Docker and Kubernetes adoption and everything else that sprung out their ecosystem, so here we are.

Yah I definitely want to be fulfilled by having to pick a health insurance plan or a car rental reservation.

Seriously, every little annoying thing in life is going to be automated, so you get to free yourself to do the things you really want to do.

Buy and sell agent, no confirmation needed. Here's my bank account. What can go wrong? I'm not categorically against the development, but I want to categorically confirm bank transactions.

What will likely happen is you give it a separate sandbox bank/credit card account with a small budget, and it transacts from that. I doubt it'll buy a house for you anytime soon.

Honestly you wouldn't believe how good these models are if you haven't tried it. They really are amazing.

This thing already exists though, it’s called a personal assistant. And since you’re already not willing to spend $400 a month on getting one, likely reveals that this is not really a thing that you really need in your life. It’s a made-up preference, I am afraid.

Yeah - feels like lunacy to me. I love the way that they get to the end of the article and then write that it doesn't really work!

I remember that John McCarthy used to condemn AI research as being a series of "look mom no hands" demos, but now we've got to "look mom I face planted". This work would be valid if it did things like :

- Describe an intelligent effect rather than "invoked an API" - so something like the system evaluating the portfolio and the market and deciding what should be sold or offering buying opportunities based on some inference (this is not a great example for many reasons).

- Measure and report the systems performance. The write-up says that the LLM fails, ok... how often?

- Describe the failure cases, provide some theory as to why some things succeeded and others didn't.

- Provide a way forward. What's next?

Without doing these things this work isn't helpful and is part of the AI/Agent/MCP hype. Basically it's Bored Apes for AI.

Like making music or drawing?

I like Go, but Typescript/Javascript really seem like the ideal languages for dealing with JSON.

Well, the JS in the name is for JavaScript :)

Yikes! I can only imagine an LLM hallucinating my portfolio to zero.

It may not hallucinate yours to zero, or mine, or franks, or Mary's, but at some point it will do it to someone. That's the issue I have with these approaches *at scale*. I'm sure one day we'll get 100.00% reliable outputs such that autonomous agents can do this, however that's not today.

The way this is done at scale is legalized front-running.

You buy order flow from "free" retail brokers like Robin Hood (as a market maker) and then literally front run ALL trades. You then tell everybody you're giving them the best price (also the only price), lol.

In other words: legalized crime.

Hmm? Either it's legal, and not a crime. Or it's illegal, and therefore a crime. What you mean is "legalized crime" exactly? Things considered legal but unethical for whatever reason?
