    Watch the https://bolt.new Reward Ceremony Live! July 26th 10AM PST on / theprimeagen #sponsored https://balls.yoga 📌 Chapters: 00:00:00 - Intro 00:01:55 - The downward trend of performance expectations 00:07:10 - The internet isn't to blame for slow speeds anymore 00:11:27 - Dial up 00:12:50 - School day routines and the reason behind modem sounds 00:18:00 - Trash was a Catfish 00:20:25 - Primes School Habits and his Moms prophetic Internet dream 00:23:58 - Teej's highschool experience 00:27:24 - Back on topic (its performance btw) WHO/WHAT is to blame 00:39:38 - Speed = Sales and WHERE is the problem 00:43:46 - Netflix BTW and WHEN performance is important 00:48:35 - Too performant and waste 00:53:14 - 'Hardware will catch up' 01:01:13 - GPU vs CPU 01:06:00 - Wrap up and closing thoughts Links: - Casey's Performance Course: https://computerenhance.com Featuring: Prime: https://x.com/ThePrimeagen Teej: https://x.com/teej_dv Casey Muratori: https://x.com/cmuratori Trash Dev: https://x.com/trashh_dev --- 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.
