I was sure human-centric GUIs would stay dominant. Some things are just faster to click through — creating a calendar event, pasting text into a file. Why talk to an agent for that?

But lately, I think I may be wrong about this.

If you're pasting a customer call transcript into a file, you're probably also updating the CRM. And adding a line to the team's weekly task list. And maybe sending a summary to the account manager. Each of these is a separate GUI, even separate apps or separate devices, a separate set of clicks, a separate context switch.

When you work with an AI agent (not ChatGPT standalone, but 2026 agents that are plugged into all your systems via API and MCP), everything changes.

You design these pathways in from the start. One action triggers multiple actions. The agent parses the transcript, checks the terminology sheet to correct names and product concepts, posts the summary into the CRM, updates the task list, and sends out notifications.

I've started doing this very recently, and it's incredible. I book my flight to the US, and dump the info to Claude Code, and it organizes the info into my trip file (for later reference), puts the flights onto my calendar (right timezone, terminal, flight number, etc.), and notifies the airport car company I always use.

All this with one prompt: "Hey I've booked my flight here's the info, pls update file gtask and notify car company". It can do this because I've wired all this into the skill.

Every file system, every CRM, every shared doc has quirks. Use bullets not paragraphs. Fill in status, action, date, participants. Use one of five acceptable values for the stage field. Put the date in ISO format.

New hires don't know these rules. Experienced people forget them, too ("hmmmm do we call the vertical internet & software or software & internet?").

Dump the whole raw transcript to an agent that knows the conventions? It fills everything in correctly, every time. I dump blobs of text from a startup's deck, memo, and the transcript of our call all into Claude Code. It reads all the rules on our investment memo format, what fields should be filled, where to create the folder and files, and does it all in one go.

So the question isn't "is it faster for a human to do this one thing?" Often it is. The question is "is it faster for a human to do this one thing plus everything that follows from it?" And increasingly, the answer is no.

The set of tasks I'd rather do manually is shrinking. Fast.
