> Amazon’s website and shopping app went down for nearly six hours this month in an incident the company said involved an erroneous “software code deployment.” The outage left customers unable to complete transactions or access functions such as checking account details and product prices.

The environment breathed a little.

I think the problem of responsibility will come for many more companies sooner than later. It is possible that some of the alleged efficacy gains by using ai are not so big anymore when someone has to be accountable for it.

I wonder how this will work in practice. Say I'm a senior engineer and I produce myself thousands of lines of code per day with the help of LLMs as mandated by the company. I still need to presumably read and test the code that I push to production. When will I have time to read and evaluate similar amounts of code produced by a junior or a mid level engineer ?
quantified•1h ago
This is an important bottleneck. You can have LLM-based reviewers help you. But unless you yourself understood your thousands of lines, it's "somebody else's" code and that somebody else cannot be fired or taken to court.

The presumably human mid-level or junior engineer has their own issues with this, but the point of the LLM is that you don't need that engineer. For productivity purposes, the dev org only needs the seniors to wrangle all the LLMs they can. That doesn't sustain, so a couple of more-junior engineers can do similar work to mature.

The accountability problem is real but I think it's slightly different from what's being described. The issue isn't just "who signs off"; it's that the reasoning behind a change becomes invisible when AI generates it. A senior engineer can approve output they don't fully understand, and six months later when something breaks, nobody can reconstruct why that decision was made. Human review works when the reviewer can actually interrogate the logic. At LLM-assisted velocity, that bar gets harder to clear every month.

I'm at a small company struggling with this problem. Fundamentally, we have a limited context and AI is capable of generating tremendous amounts of output that exceed our ability to deeply process.

I find myself context-switching all the time and it's pretty exhausting, while also finding that I'm not retaining as much deep application domain knowledge as I used to.

On the surface, it's nice that I can give my LLM a well-written bug ticket and let it loose since it does a good job most of the time. But when it doesn't do a good job or it's making a change in an area of the codebase I'm not familiar with, auditing the change gets tiring really fast.
