I get why DHH would be really happy about getting rid of engineers. It's less clear how this isn't a little bit gloomy for the engineers.

Is the idea that they'll switch to doing "product owner" roles overseeing agents? I don't see that employing the same number of people or paying as well as engineering used to.

To be honest I expect that that role to suit different people to those that used to be engineers.

If this feels gloomy to some people, it's because it is.
