Software Engineering in the GenAI Era: 8 Myths and Truths

As generative AI (GenAI) tools become essential elements of software development workflows, various misconceptions about their performance and impact have spread. Often there is an expectation that if AI tools become smarter, all problems in the development process will disappear, but the reality on the ground is different. In practice, factors such as organizational adoption speed, human review capability, and understanding of fundamental design principles act as more decisive bottlenecks than tool performance, and non-routine knowledge activities—not captured by simple coding productivity—determine the final value of software. This article summarizes eight myths frequently observed in developer communities and industry settings, and examines the truths behind them.

Myth 1: If AI tool performance is excellent, adoption will be smooth

Many organizations expect a sudden surge in productivity as soon as they adopt cutting-edge generative AI tools. However, according to an industry research paper published in July 2026, “Faster than the Team, Faster than the Customer: Tool Integration, Collaboration, and Organisational Lag in AI-assisted RE”, when applying generative AI to requirements engineering (RE), the actual bottleneck was not a lack of tool features but organizational adoption delays and workflow integration issues. No matter how excellent the tool, if team collaboration processes, existing documentation systems, decision-making authority, etc., do not change, it can actually slow things down. Ultimately, change management and phased integration strategies are more important than technical performance.

Myth 2: AI-generated code guarantees high quality on its own

There are many cases where it is mistakenly assumed that if the generated code has no syntactic errors, it can be applied to the product immediately. However, the source of high-quality software is not the code itself but the human experience and judgment that validates it and refines it for the context. As seen in the reliability-validity paradox, AI models can produce consistent results (reliability) for a given task but still have limitations in meeting real-world complex constraints or non-functional requirements (validity). Therefore, automatically generated code must always go through learning loops such as peer review, testing, and architecture verification.

Myth 3: Developers no longer need to know coding principles

In an era where AI writes code for you, is there still a need to study fundamentals like data structures and algorithms? Therein lies the big misconception. To evaluate the quality of AI-generated code, make design decisions, and diagnose performance bottlenecks, a solid understanding of fundamental principles is essential. In fact, even in educational settings where AI writes assignments or reports for students, there are growing calls to shift from memorization to developing thinking, reviewing, and judgment skills. The more sophisticated the automation tools become, the more the expertise to critically analyze their output becomes a greater competitive advantage.

Myth 4: AI can completely replace requirements engineering

When AI quickly writes a draft requirements document, it may seem like requirements engineering as a whole can be automated, but this is also an exaggerated expectation. Along with the aforementioned organizational lag issues, processes such as clarifying ambiguous needs among stakeholders, negotiating priorities, and trade-off analysis still need to be centered on human communication and experience. AI tools excel at repetitive, rule-based research and drafting, but final decisions and experience-based reviews must still be performed directly by developers and stakeholders to achieve responsible outcomes.

Myth 5: Productivity can be measured solely by code generation speed

The approach of evaluating developer productivity simply by how many lines of code are produced per day is still prevalent even in the generative AI era. However, in software engineering, real value comes from non-routine knowledge activities such as failure analysis, exploring alternatives, architectural decisions, prototyping experiments, and evolving judgment. As AI accelerates code production, the time invested in these thinking-centric activities becomes relatively more important, so evaluation criteria must also change.

Myth 6: AI drafts do not need human review

In some teams, a practice is emerging of accepting AI-generated documents or code drafts as they are. However, even for highly repetitive and rule-defined tasks, final responsibility lies with humans. The proper sequence of automation is to assign research and drafting to AI tools, and then have humans perform review and approval based on actual experience and judgment. Skipping this step can accumulate errors that later lead to greater costs.

Myth 7: AI adoption is a purely technical issue

Not a few organizations view generative AI adoption as a purely technical challenge and hand it over solely to engineering teams. In reality, however, it requires broad changes in culture, communication, accountability, training, and even performance evaluation systems. Even a technically perfect tool can fail due to psychological resistance or ambiguous workflows. Therefore, rather than emphasizing technical excellence alone, equal investment must be made in change management and organizational learning.

Myth 8: The developer’s role shrinks to simple coding

Finally, there is a fear that generative AI will reduce the developer’s role to just coding tasks. Quite the opposite. Freed from repetitive and tedious coding, developers can focus on higher-level design, critical review, complex problem solving, and stakeholder collaboration. Much more strategic thinking is required than before, and the ability to oversee the entire software lifecycle becomes even more valued.

Thus, to realize the true potential of generative AI, we must not simply adopt tools but focus on designing human thinking and organizational learning loops. This is because the human judgment process of reviewing and improving AI-generated drafts, more than the speed at which AI produces them, determines the final quality. To systematize such review loops, it is a good idea to utilize a human-in-the-loop review and archive layer like md-log, which allows comfortable review of AI outputs on web, phone, and tablet, and accumulates immutable versions with each save to leave a collaboration history. We hope you will build a harmonious collaboration system between technology and humans in step with the pace of change.
