Swizec Teller argues that the future of software engineering lies in Site Reliability Engineering (SRE), emphasizing that while writing code is straightforward, maintaining operational excellence is where true engineering value lies. As startups scale, the ability to run services reliably becomes paramount.

The article highlights the challenges faced by those who build one-off solutions, such as Joe from accounting, who initially finds joy in automating his tasks but eventually struggles with the complexity and maintenance of his custom-built tools. This illustrates the 'computer disease'—where the fun of building overshadows the critical work of maintaining systems.

Teller suggests that operational excellence, rather than just coding, is what companies truly hire for. He outlines key considerations such as uptime, defect rates, and recovery times, which are often overlooked in the early stages of software development. These factors define whether a service is trustworthy and reliable over the long term.
