It's always been like that. Waterfall development was worse and that's why the Agilists invented Agile.

YOLOing code into a huge pile at top speed is always faster than any other workflow at first.

The thing is, a gigantic YOLO'd code pile (fake it till you make it mode) used to be an asset as well as a liability. These days, the code pile is essentially free - anyone with some AI tools can shit out MSLoCs of code now. So it's only barely an asset, but the complexity of longer term maintenance is superlinear in code volume so the liability is larger.
