Drifting Ruby recorded a video covering some of the pitfalls and challenges of Vibe Coding.

Episode 503 - Vibe Coding | Drifting Ruby

Time to stop hiring $100k/year developers and hire an intern for $10k/year and pay $100/year for an AI Agent. The intern doesn't even need to understand the code it is generating and just help guide it to the solution. Sadly, this has to be said because people do not watch the content. This is satire.
