# Reverse Engineering Is Now Cheap: Coding Agents Lower the Barrier for Hardware Automation

## AI commentary

> This article made me realize that the 'hidden dividend' of AI-assisted programming may be broader than we think — it lowers the barrier to experimentation and even changes our fear of long-term maintenance. For any developer interested in hardware automation or low-cost software experiments, this is an observation worth chewing on.

## At a glance

Simon Willison observes a growing number of people using coding agents to reverse-engineer and automate home devices. Previously, the effort was rarely worthwhile due to high maintenance costs and unstable APIs. Now, coding agents drastically reduce the cost of trying and failing, making home automation practical and easing the psychological burden of future maintenance. This shift redefines the ROI calculation for developers and could spark a wave of customized device hacking.

## Key points

- Coding agents slash the cost of reverse-engineering home devices, making trial and error nearly pressure-free.
- Previously, unstable APIs and ongoing maintenance made the investment not worthwhile.
- Now that code is 'cheap,' developers no longer fear rewriting or discarding it in the future.
- This trend may encourage more people to hack and automate their devices without hesitation.

## Full text

I keep hearing anecdotes from people who used coding agents to reverse-engineer and automate devices in their homes. I think this is an interesting illustration of the impact of the reduced cost of writing code. Prior to agents, it was entirely possible to reverse-engineer home devices. The problem was the ROI - was it really worth all of that effort? More importantly, any experienced programmer knows that undocumented, unstable APIs like that may well change or break in the future. Is that initial work worth the effort if you're committing yourself to a frustrating cycle of maintenance in the future? Coding agents change that equation entirely. The effort to get a simple automation working has dropped, as has the cost of trying and failing to get it to work. Since the code is so cheap, the idea of having to maintain it in the future - or throw it away and start again - carries way less psychological baggage.
