9. An exceptionally interesting point in time ▪ ▪ ▪ ▪ ▪ ▪ The practice of software development continues to evolve Many developers express a feeling of uncertainty How did we get here? Where are we going? Where do I fit in? How do we prepare? A software developer surrounded by question marks in a modern Chinese cartoon style © 2025, Amazon Web Services, Inc. or its affiliates.

19. Why developer tools matter ▪ ▪ ▪ Tools let us “stand on the shoulder of giants” (Isaac Newton) Tools build on and compose with other tools Tools improve with (and take advantage of) available compute power, and grow more powerful themselves as a result A detailed illustration, in a traditional Chinese style, of giants and regular sized humans using a variety of hand tools such as hammers and wrenches © 2025, Amazon Web Services, Inc. or its affiliates.

39. Some thoughts Development model: ▪ Old school - “Digital” – reference manual says it all, read it and you are ready ▪ New school - “Analog” – model has capabilities, strengths, weaknesses to explore Applications: ▪ Old school – App is precious, curated, maintained for years and decades ▪ New school – App is short-lived, rebuilt regularly from scratch © 2025, Amazon Web Services, Inc. or its affiliates. All rights reserved.

40. Some more thoughts Data and schemas: ▪ Spans multiple app generations, more valuable and precious than ever Developers ▪ Old school – Specialized skills, part of a large team ▪ New school – Generalists, adaptable, resourceful, self-sufficient © 2025, Amazon Web Services, Inc. or its affiliates.

42. Reading code is an essential skill • To date we have been taught to write, but not to read • AI-assistance makes reading and understanding code more important than ever before • My golden rule for production-quality AI-assisted programming is that I won't commit any code to my repository if I couldn't explain exactly what it does to somebody else. – Simon Willison © 2025, Amazon Web Services, Inc. or its affiliates.
