In this episode of The Standup, we tackle one of the most frustrating aspects of modern computing: why everything feels so sluggish despite having incredibly powerful hardware. Casey Muratori joins us to share his perspective on performance culture and how we've collectively lowered our standards over the past two decades.
From nostalgic stories about dial-up internet and modem sounds to serious discussions about software architecture, this conversation covers the technical, cultural, and business factors that have led to today's performance problems. We explore real-world examples from Netflix, discuss the impact of layered abstractions, and examine how corporate development pressures contribute to the problem.
Key topics include:
- How performance standards have declined while hardware has improved exponentially
- The role of abstractions and frameworks in creating performance bottlenecks
- Real Netflix case studies showing the complex relationship between performance and user behavior
- Why the "hardware will catch up" mentality is fundamentally flawed
- The difference between GPU and CPU performance paradigms
- How AI might make performance problems even worse
- Potential solutions through better substrate design
Whether you're a developer frustrated with slow tools, a user wondering why your powerful computer still feels sluggish, or someone interested in the intersection of technology and culture, this discussion offers valuable insights into one of computing's most persistent challenges.

Could Your Company Survive a Google Outage?
Last week, Google Cloud went down—and with it, a massive chunk of the internet. In this episode of Standup, we’re joined by security expert Low Level Learning to break down what actually happened, how a single null pointer crashed Google’s management plane, and why Cloudflare and other services followed. We also go deep on software fuzzing, dependency risk, fail-open systems, and the absurd reality of internet-connected lamps.
