1. A person building alternatives to photoshop single handedly: https://gizmodo.com/someone-vibe-coded-a-free-knockoff-of-ad...
2. The abundance of game decomps and recomps becoming available. Literally dozens of example in this space.
3. Reverse engineering of obscure software. A ton of oppertunities lie here.
4. As this posts indicate, severely accelerating existing software by re-writing it in language that are not terrible for performance.
5. Analyzing large volumes of unstructured information.
6. Creating one-off engineering and scientific tools.
7. Beating essentially all traditional Linux distribution, see Omarchy.
8. A personal example: I'm remaking the engine of an old game commercial game in rust.
I'm honestly a bit taken aback that this question is even asked. The volume of software is exploding and the power of the individual has increased a hundredfold.
My thought was LLMs accelerate the best and worst of development, but what couldn’t be done (outside of a large lab or company) by regular humans with an infinite time scale?
You don’t need an LLM for that, just some dedicated time for it. Also your phrasing needs a lot of work. I recommend the Dale Carnegie books on communicating with others.
