This is gaslighting. We're only a few years into coding agents being a thing. Look at the history of human innovation and tell me that I'm unreasonable for suspecting that there is an iceberg worth of unmitigated externalities lurking beneath the surface that haven't yet been brought to light. In time they might. Like PFAS, ozone holes, global warming.
The other factor that gets glossed over is that llms create a financial incentive to create cleaner code, with tests, because the agent that you pay for will be more efficient when the code is easier to understand, and has clear patterns for extensibility. When I do code with llms, a big part of it is demonstration, i.e. pseudocoding a pattern/structure, asking the model if it understands, and then having it complete the pattern. I've had a lot of success with this approach.
Right, this is the kind of discussion we're having on my team: suddenly all of the already good engineering practices like good observability, clear tests with high coverage, clean design, etc. act as a massive force multiplier and are that much more important. They're also easier to do if you prioritize it. We should be seeing quality go up. It's trivial to explore the solution space with throwaway PoCs, collect real data to drive your design, do all of those "nice to have" cleanups, etc. The people who assume LLM = slop are participating in a bizarre form of cope. Garbage in, garbage out; quality in, quality out. Just accept that coding per se is not going to be a profession for long. Leverage new tools to learn more, do more, etc. This should be an exciting time for programmers.
This will not happen until companies decide to care about quality again. They don't want employees spending time on anything "extra" unless it also makes them significantly more money.
People might still code by hand as a hobby, but I'd be surprised if nearly all professional coding isn't being done by LLMs within the next year or two. It's clear that doing it by hand would mostly be because you enjoy the process. I expect people that are more focused on the output will adopt LLMs for hobby work as well.
