Yes, they're certainly squeezing 500 lines of functionality into 250,000 lines of code. Agents are great at this.

So where is all that new software? My laptop and phone run essentially the same software as 2 or 3 years ago. Yes there were some minor updates to some apps, but nothing faster than in the years prior.

Where does all that supposed productivity go?

I mean these guys are not even pretending to be reviewing the code.

It just gets “reviewed” by an LLM, which will find a nitpick while ignoring the huge fire in the core of the design, force the planner to make even more sloppy code to cover for an irrelevant test case. Rinse old tokens and repeat until you hit limits.

What kind of applications are people building that involve 250k loc a week? Genuinely trying to understand this.

Can the users of the software even keep up at that point? We may have reached diminishing returns on software production, and not enough impact on the rest of the process.
