In this follow-up episode of the DevReady Podcast, Anthony Sapountzis sits down again with Bill Lennan, Founder of 40 Percent Better, to explore how AI is changing software development, tech careers, and business decision-making. Bill brings a grounded, executive-level view on what is working, what is not, and why the AI boom feels both exciting and unsettling for teams worldwide. Connect with Bill on LinkedIn for more of his thinking on leadership, technology, and practical innovation. Together, Anthony and Bill unpack what staying relevant in an AI-driven tech industry really requires, and why human skills remain central to future-proofing your career. They begin by tackling the rapid shifts happening across the industry and the myth that AI can already replace great engineers. Bill explains that while AI can speed up prototyping, high-quality software still needs experienced developers to review outputs for reliability, maintainability, and security. He also points to a growing adoption barrier that executives keep raising: the economics of AI remain unclear. Flexible and unpredictable operating costs make it hard for companies to plan return on investment, which slows rollout even when the technology looks promising. Anthony then shares what he sees in the wider conversation: founders celebrating “vibe coding” as if it removes the need for engineers, while developers warn about security risks and brittle code. Bill feels this debate echoes earlier technology waves like the early internet, where big ideas arrived before infrastructure, standards, and safeguards were ready. The pattern is familiar: early optimism, unexpected failures, then gradual maturity. Both agree that AI will improve and start prompting builders about security and trade-offs more like a senior engineer, but it will still need human judgement to align solutions with real user value. From there, the discussion moves into AI’s limits in human-centred work. Anthony argues that AI lacks emotional intelligence and empathy, which makes it unsuitable for roles that require care and context, such as nursing. Bill expands this to a broader point about data quality: AI reflects what humans have studied and published, and much of human behaviour research is narrow, culturally limited, or based on small sample sizes. That means AI can confidently generate answers that are incomplete or biased, and people’s tendency to accept written outputs at face value only worsens the risk through confirmation bias. Finally, they turn to career resilience. Bill urges people in tech, especially students, to build a broader skill set that includes communication, curiosity, and user-focused problem solving, because the market now has a surplus of programmers. AI may keep pushing coding up the abstraction ladder, but the ability to work with people, understand real needs, and lead collaborative teams will remain a competitive edge. They also touch on AI’s hidden energy costs, the learning downside of overreliance on tools, and even the value of practical life skills as a hedge against automation. The takeaway is simple: in a fast-changing AI era, soft skills and adaptability are not optional extras, they are the safest long-term investment. #DevReadyPodcast #AIinSoftwareDevelopment #SoftwareEngineering #TechCareers #AerionTechnologies #AIAdoption #VibeCoding #FutureOfWork
