How would you start to learn coding today?

I'm a PM and Product Designer looking to transition into launching my own products. While I have basic programming knowledge, I'm trying to be strategic about what technical skills to develop given the current AI landscape.

I'd love to hear your thoughts on what technical skills would give me the best value-for-effort ratio as a solo founder in 2025. Should I focus on learning prompt engineering and AI integration, dive deeper into a specific programming stack, or perhaps take a different approach entirely?

Appreciate any insights from those who've been in similar positions!
