"I feel like working with agents is a lot more productive, but a lot less fun." Charlie Marsh tweeted this and people won't stop quoting it back at him. On The Test Set, he gets into why — and it's not really about fun. It's about the vibe being off. We're in this weird in-between where engineers are stitching together agent outputs, copy-pasting PR comments into Claude Code, and reviewing code they didn't write but are somehow responsible for. It's giving duct tape. Charlie says he's hopeful we'll figure out what building software actually looks like in this new era — but right now? We're not there. He also drops that his opinions on literally all of this are radically different from four months ago, which honestly says everything about how fast this is moving. Full conversation now live.
