Great question! Electricity was discovered (because it already existed in nature, like in lightning). But the lightbulb was invented (because humans created it from scratch). ⚡💡
What is the difference between "Cutting-edge" and "State-of-the-art" from the last lesson?
They are very similar! Both mean highly advanced. "Cutting-edge" focuses more on being the newest, most innovative idea (maybe still in testing). "State-of-the-art" focuses on being the best equipment currently available on the market. 📱
Is "Artificial Intelligence" singular or plural? Do I say "AI is" or "AI are"?
It is an uncountable noun (singular). So, you should say "AI is changing the world." 🤖
