Positives

LLMs can significantly enhance tooling efficiency, allowing for quick implementation on lower-spec computers, which is crucial for resource-constrained environments.
The ability to achieve substantial CPU performance boosts and RAM reductions through efficient data structures highlights the potential for TUIs to optimize resource usage.

Concerns
