Two Minute Papers — 'Is Software Over?'
Two Minute Papers asks 'Is Software Over?' and links four projects: MirrorCode, where AI agents rebuild programs from behaviour alone, the REMEND decompiler, WebUI-95 and PhotoCraft, an open-source Photoshop rebuild in Rust.
Two Minute Papers looks at AI that can rebuild existing software without seeing its source code.
What is it?
'Is Software Over?' is a Two Minute Papers video uploaded on November 10, 2026. Its description links four projects: the MirrorCode benchmark paper, the REMEND neural decompiler on Hugging Face, a WebUI-95 paper and the PhotoCraft image editor on GitHub.
How does it work?
In MirrorCode, AI agents must reimplement 25 existing programs, from Unix utilities to interpreters and compression tools, without the source code, and match the original output exactly on held-out tests; the strongest model scores 56%. REMEND recovers math equations and their order of operations from compiled binaries with a transformer of up to 12 million parameters.
Why does it matter?
If agents can rebuild a program from its behaviour alone, copying and replacing software gets much cheaper. MirrorCode also shows the cost: one attempt on a large task took $2,600 over 19 days. PhotoCraft, a clean-room Photoshop reimplementation in Rust with 78.4k GitHub stars, is the kind of rebuild the question points at.
