Companies may soon discover that owning the code is no longer equivalent to owning the system, as AI-generated software may be maintained efficiently through continued AI mediation rather than human understanding. This shift changes the meaning of ownership, making it a new strategic vulnerability that companies must address through AI continuity plans.

The experiment found that using expert personas in LLM prompts had no effect on accuracy, but a negative effect on cost and speed, depending on the model. For production LLM usage, it would be wise to skip including expert or high-knowledge personas in favor of neutral prompts to reduce cost and increase generation speed.

Computer science education is outdated, prioritizing foundational knowledge over practical skills, whereas the industry demands hands-on experience with modern tools and technologies. By flipping the order, teaching students to build useful software first and then introducing deeper computer science concepts, educators can better prepare students for the demands of the job market.
