Software engineers often focus on non-essential aspects, spending 80% of their time on unnecessary features.Software is often used to test hypotheses, leading to many startups failing due to incorrect assumptions.Validating hypotheses requires statistical relevance and adapting to change quickly.Having software that can adapt well to changes is crucial in validating hypotheses.Engineering software that can handle change effectively is a challenging task.Contracting technical debts is common in competitive markets, akin to financial investors managing risks.Learning from mistakes is essential, and experienced engineers know which mistakes to make given the circumstances.Abstraction in software development can help in delivering solutions faster by focusing on essential aspects.Change is a fundamental requirement in coding, questioning the need for scalability at every stage of development.Focusing on adaptability rather than scalability may lead to validating more hypotheses efficiently.
