Today Quincy Larson interviews Carl Brown, who runs the Internet of Bugs YouTube channel and has worked as a dev at Amazon, IBM, Sun Microsystems, and startups for over 37 years.

We talk about:
- The hype versus the utility in LLMs and agent code generation tools
- Why you might want to target developer jobs at smaller companies, and how these differ from "big tech"
- How everyone will face agism eventually. Carl argues that a consulting career is a great escape hatch.

A podcast interview with Carl Brown (Internet of Bugs), a 37-year software industry veteran, covering his views on LLMs as sophisticated search/compression tools, the parallels between the current AI investment bubble and the dot-com era, and why integration testing is the most critical developer skill. Carl argues LLMs speed up coding but reduce code quality, explains the limitations of TDD versus end-to-end testing, and discusses how experienced developers will be needed to debug AI-generated code. He also covers fuzzing, the value of diff-based debugging, and career advice for developers navigating a rapidly changing job market.
