TFA is right to point out the bottleneck problem for reviewing content - there’s a couple things that compound to make this worse than it should be -
The first is that the LLM outputs are not consistently good or bad - the LLM can put out 9 good MRs before the 10th one has some critical bug or architecture mistake. This means you need to be hypervigilant of everything the LLM produces, and you need to review everything with the kind of care with which you review intern contributions.
The second is that the LLMs don’t learn once they’re done training, which means I could spend the rest of my life tutoring Claude and it’ll still make the exact same mistakes, which means I’ll never get a return for that time and hypervigilance like I would with an actual junior engineer.
That problem leads to the final problem, which is that you need a senior engineer to vet the LLM’s code, but you don’t get to be a senior engineer without being the kind of junior engineer that the LLMs are replacing - there’s no way up that ladder except to climb it yourself.
All of this may change in the next few years or the next iteration, but the systems as they are today are a tantalizing glimpse at an interesting future, not the actual present you can build on.
