I've spent a lot of time with LLMs for the last two years. Something I've tried, almost for decades, is to learn enough CUDA programming to be productive with it when needed. About 6 months ago, after again banging my head against it for weeks, something finally clicked and I feel like I've overcome the initial step of at least grokking the needed ideas so I know where to go next, and I can actually write + compile + use kernels made for my use cases. I won't claim to understand everything, but I couldn't do what I can today, before I learnt the things I now know.
~2 years ago, because of my very weak math foundation, I basically said "Well, CUDA looks really interesting and really fun, but it's too difficult, lets focus on other things", even after reading some starting resources and stuff. But, by asking countless of dumb questions to LLMs, forcing it to steer me in the right direction, when I'm otherwise just driving on the highway or what not, I finally feel like I have a grasp on something I earlier only dreamed about understanding, and I'm able to be productive with it now.
