Free learning resources for tech and AI that are actually good, not just padding with ads - help needed

[Hollow Coder]

Q: Where can I learn AI, quantum, programming, or related topics for free without the content being padded garbage?

A: Fast.ai for practical deep learning, genuinely world class and free. MIT OpenCourseWare for rigorous foundational content. Khan Academy for maths prerequisites. The Odin Project for web development. CS50 from Harvard on edX for computer science fundamentals. For quantum specifically IBM Quantum Learning and the Qiskit documentation and tutorials. 3Blue1Brown on YouTube for mathematical intuition. Andrej Karpathy's Neural Networks Zero to Hero series on YouTube for understanding transformers from the ground up

Fast.ai deserves to be higher on more people's lists. Jeremy Howard's teaching style makes difficult concepts accessible and the practical first approach actually works

3Blue1Brown's Essence of Linear Algebra series is the one I send to everyone who needs to understand the maths underlying AI. The visualisations are genuinely irreplaceable

[Cass82]

CS50 is where I started and I still recommend it years later. The teaching quality is exceptional and David Malan's production values make it feel like you are getting something premium

[Fan22]

Karpathy's makemore and nanoGPT videos are the ones that took me from understanding GPT conceptually to understanding it mechanistically. Huge difference

[IronFist21]

IBM Quantum Learning for quantum specifically is genuinely good and free. The Qiskit tutorials go from hello world to variational quantum eigensolvers in a structured way

MIT OCW 6.006 Introduction to Algorithms is the course I wish I had done before getting into professional software development. Still free, still excellent

[Jarvis]

The free tier of Coursera Machine Learning by Andrew Ng is technically audit only but the audit content is substantial and more than enough to learn from

[Sophie83]

Exercism.io for language practice across 70 programming languages with mentor feedback. Completely free, community supported, and more useful than most paid platforms

[veritas.io]

The quality gap between free and paid learning content has basically collapsed. Almost every top tier course has a free equivalent if you know where to look
