Vibe Coding Killed Cursor

Anton Morgunov - Cursor is dying because cost-optimization forces models into tunnel vision. RAG agents fail because they only see what they search for. The superior workflow for 2026 is massive context windows (gemini 2.5 pro) and manual control. Stop letting agents hide code from the model.

Extensibility: The "100% Lisp" Fallacy
kyo.iroiro.party

Kana - So, I've seen some articles promoting Emacs-like editors written in Lisp languages, and one of the most common arguments seems to be: "it's written in This Lisp and also scriptable in This Lisp, and that gives it great extensibility." 1 It's not wrong, but I think it does overlook a few things. By the way: Happy New Year!

Building an internal agent: Code-driven vs. LLM-driven workflows
lethain.com

When I started this project, I knew deep in my heart that we could get an LLM plus tool-usage to solve arbitrarily complex workflows. I still believe this is possible, but I’m no longer convinced this is actually a good solution. Some problems are just vastly simpler, cheaper, and faster to solve with software. This post talks about our approach to supporting both code and LLM-driven workflows, and why we decided it
