The million dollar (perhaps literally) question is – could @kentonv have written this library quicker by himself without any AI help?
The million dollar question is, what are the unintended, unpredicted consequences of developing this way?
If AI allows me to write code 10x faster, I might end up with 10x more code. Has our ability to review it gotten equally fast? Will the number of bugs multiply? Will there be new classes of bugs? Will we now hire 1 person where we hired 5 before? If that happens, will the 1 person leaving the company become a disaster? How will hiring work (cuz we have such a stellar track record at that...)? Will the changing economics of creating software now make SaaS no longer viable? Or will it make traditional commercial software companies no longer viable? Will the entire global economy change, the way it did with the rise of the first tech industry? Are we seeing a rebirth?
We won't know for sure what the consequences are for a while. But there will be consequences.
