 ### Generative AI
 
-Generative Artificial Intelligence (**GenAI**), a version of Artificial Intelligence (**AI**) that is good at generating content: text, images, sounds, videos, code, etc.
+Generative Artificial Intelligence (**GenAI**) is a version of Artificial Intelligence (**AI**) that is good at generating various content: text, images, sounds, videos, code, etc.
 
-The previous version of GenAI, refered to as AI, was based on Deep Neural Networks (**DNN**), which are brain-inspired math equations optimized useful for content classificaiton. For example, it enabled computers to identify if pixels in an image represent a cat, or understand if text is written in Spanish.

For example, it enabled computers to identify if pixels in an image represent a cat or dog, or if some text is written in Spanish or English.
 
-GenAI uses AI in the opposite way -- not to classify, but to generate content on its own. For example, generate pixels for a cat image, or generate text in Spanish.
+GenAI uses AI in the opposite way -- not to classify, but to generate and create new content. For example, to generate a pixel image of a cat, or a response to some text in Spanish. A response from ChatGPT would be another example of GenAI in action.
 
 Head next to the [Deep Neural Networks](genai/dnn) section to learn the foundations that lead us to Generative AI.
 
 ### Generative Apps
 
 Generative Applications (**GenApps**) are software applications (**apps**) written with code that make use of GenAI.
 
-ChatGPT popularized using chatbots as the main interface for these GenApps, other services like MidJourney also used chat interfaces like Disscord, but we are starting to see other interfaces like ChatGPT 4o that run in mobile phones and can understand voice and video without a chat interface. In the not so distant future, we might see GenApps that run in Zoom or even robots like Tesla's Optimus.

-For example, even if an AI or a robot was capbale of flying a airplane autonomously, developers might want to write code that double checks that the landing is safe, connects to the best weather services, or provides flight updates to passengers.

-We don't know exactly what the new GenApps will look like and how our jobs or world will transform, but we are optimistic that GenApps will help us solve the hard problems the world is facing in healthcare, education, climate, energy, space exploration, entertaiment, and so on.
