Create a vibrant and eye-catching YouTube thumbnail for a video about artificial intelligence. The background should be a sleek, modern gradient of blue and purple. In the center, place a futuristic robot head with glowing eyes, surrounded by circuit patterns. Add a bold, white title at the top saying 'Mastering AI' and a smaller, bright yellow subtitle below it saying 'Unlock the Future of Technology'. Incorporate icons of AI elements like neural networks and data charts around the robot to add context. Ensure the design is clean, high-tech, and visually appealing to attract viewers
