Not so locked in any more

14th May 2026

This Mitchell Hashimoto quote about Bun migrating from Zig to Rust reminded me of a similar conversation I had at a conference last week.

I was talking to someone who worked for a medium sized technology company with a pair of legacy/legendary iPhone and Android apps.

They told me they had just completed a coding-agent driven rewrite of both apps to React Native.

I asked why they chose that, given that coding agents presumably drive down the cost of maintaining separate iPhone and Android apps.

They said that React Native has improved a lot over the past few years and covered everything their apps needed to do.

And... if it turned out to be the wrong decision, they could just port back to native in the future.

Like Mitchell said:

Programming languages used to be LOCK IN, and they're increasingly not so.
