Mark Zuckerberg Launches Muse Code AI for Full Software Engineering
Mark Zuckerberg is the boss of a big technology company called Meta.
He has introduced a new computer tool called Muse Code.
Muse Code is a robot helper that can write computer programs all by itself.
Instead of just giving hints to human coders, it plans changes, writes the code, and checks that everything works.
It is built to work on very large coding projects and can even split big jobs among several robot helpers at the same time.
Meta says these helpers can work together without getting in each other's way, like building six game features at once.
The tool is powered by a new model called Muse Spark 1.2 and is still in an early testing stage called beta.
Some people in the tech world think tools like this will change programming forever.
Boris Cherny, who helped build another coding tool called Claude Code, thinks programmers may soon stop using their old coding programs.
He even says he hasn't written any code by hand since November 2025.
Meta CEO Mark Zuckerberg announced the beta launch of Muse Code, a terminal-based AI coding agent that handles complete software engineering tasks across large repositories.
Muse Code runs on Meta's Muse Spark 1.2, a coding-focused AI model, and competes with Anthropic's Claude Code and OpenAI's Codex.
The tool keeps background AI agents working throughout a session and can split large tasks among multiple sub-agents in isolated workspaces, with Meta testing it on six game features at once without conflicts.
Meta logs every request, tool call, and code edit so the system can resume after failures, and reported over 1,000 tool calls in a 24-hour kernel optimisation test on NVIDIA Hopper hardware.
Anthropic's Boris Cherny, creator of Claude Code, predicts software engineering jobs will disappear and that developers will stop using IDEs such as VS Code and Xcode by the end of the year.

AI agents replace human engineers
Traditional tools remain the standard
Future of software engineering jobs
AI agents replace human engineers
Boris Cherny, creator of Claude Code, claims all software engineering jobs will become obsolete starting this year and that AI agents can manage virtually every stage of development; he says he has not manually written a line of code since November 2025.
Traditional tools remain the standard
Software engineers and their established tools have been the standard for years, and Cherny's statements are characterized in the article as bold claims about the future rather than established outcomes.
Terminal-based AI agents vs. IDEs
AI agents replace human engineers
Cherny predicts people will no longer use IDEs by the end of the year and argues that building traditional graphical programming interfaces is pointless because AI models are evolving so rapidly.
Traditional tools remain the standard
Integrated development environments such as Microsoft's VS Code and Apple's Xcode have been the standard tools for developers for years, and their imminent replacement is not demonstrated.
