Idk if someone paying attention to how 2025 and 2026 have gone thinks that by 2028 we will be backing off of agenting coding that is wild. Like the other comment says: future models refactor the code of older models.
if you were paying attention you would've noticed that between 2025 and 2026 the pricing of these things have somewhat changed. How does the extrapolation look with that?
You can use LLMs heavily without ever actually "vibe coding". I do think to the degree "vibe coding" continues to exist there will always be work to do in turning some portion of vibe coded work into more robust production quality code. You can still use LLMs to do this you just have to maintain control over architectural choices.
