Builders urged to learn engineering fundamentals before using agents
Agent outputs can look correct while hiding suboptimal or fragile solutions, so evaluation and engineering judgement stay essential even as coding assistants improve. Developers and technical leads adopting tools like Claude Code should invest in fundamentals — evals, architecture and concurrency — rather than delegating decisions entirely. The exchange offers a practical counterpoint to messaging that coding skills are no longer needed.
Elvis Saravia of DAIR.AI posted on X that builders relying on AI agents still need core engineering knowledge in evals, infrastructure, architecture, scaling search and sandboxes.
He warned that agents can produce broken results that appear to work through hidden hacks, without the judgement of someone with domain expertise.
Quoting Ben Dickson, the post argues that real builders use tools like Claude Code to implement engineering decisions they already understand, such as spotting concurrency bottlenecks.
The thread encourages continued learning of fundamentals like algorithms, where optimal versus suboptimal solutions matter.
I agree. Learn the fundamentals, folks! If you plan to be a solid builder using agents, this is a really important point. There is no way around it. I have recently started digging deep into evals, infra, architecture, scaling search, and things like sandboxes @dair_ai using agents, and I can tell you that it's really easy to produce absolute slop. You could be using the most advanced models today confidently and not know that everything is broken because the agents somehow got it to work through some weird hack. Agents don't have the taste of someone with proper domain expertise. And I don't think that's coming anytime soon. But something you learn in algorithms (one important fundamental subject) is that solutions can be optimal or suboptimal. In other words, many ways to transform inputs to get the same outputs. Agents don't give a crap about that and sometimes feel like they are flipping a coin. I can tell you that much. Stay learning, folks. This is the way. Ben Dickson @bendee983 The AI influencers are telling you that you don't need to learn coding and engineering since Claude Code will do all the work and you just need to give it some very high-level command. Meanwhile, real builders are making important engineering decisions and using Claude Code to implement those decisions. Without engineering chops, you won't even think about the concurrency bottleneck, let alone spot it, and even less so fix it with AI. Learn the fundamentals folks. I can't say this enough. 🔗 View Quoted Tweet📊 3 ⚡
