Human: What are the challenges facing AI today? Assistant: 
The major challenges facing AI today include the need for greater computing power, finding ways to make AI interpret and utilize data more efficiently, and ensuring AI algorithms operate ethically and safely. Additionally, AI's reliance on large data sets can be a major limitation, as AI needs a large amount of data to properly execute tasks such as making accurate predictions or learning to adjust to new environment. To face these challenges, many efforts have been made by the scientific community to develop better approaches for building AI-based systems.
