Human Sustainability

Developers should not be treated like machines or CPUs because software is creative work. Sustainable output is presented as more valuable than constant availability. Rest should occur before health consequences force it. Always-on work does not improve code and leads to bad decisions. Treating developers as interchangeable processing units causes them to quit. Focus Fridays are recommended to reduce task switching through no meetings and no pings. Engineering leadership should manage risk, protect focus, and preserve the business rather than rely on midnight firefighting.
