They're not lying. With AI coding agents, they can not only 100x but 1000x their output, which is 1 year's worth of code in 0.365 days.

However, 1000x output doesn't mean 1000x productivity. When you defer this amount of your work to the agents, you lose all semblance of control. You are at the mercy of whatever the LLM thinks is useful. There is no way you can fully understand what the AI is doing.
