    tldr:

    dhh says 37signal's apps for Hey (their email platform moving to native)

    backend for their email platform is now Rust - written by agents

    says Rust produces small binaries - cutting number of servers needed from 110 to 10. hell they could serve peak traffic on a Raspberry Pi

    says now that agents write all the code - use faster / native languages.

    rails or ruby hardly get a mention besides that they might be well placed to capture web apps written by agents.

      also worth noting that hotwire is dead according to DHH in this talk. The rendering html server side is old way now
