How wonderful it is to have this opportunity to speak with you. I'd like to start with a bold proclamation - Artificial Intelligence, or AI as we often call it, is no longer just a futuristic vision. It's here. It's now. It's changing the way we live, work, and play, in ways that are profound and, I dare say, exciting.

AI is everywhere around us, from personal digital assistants like Amazon's Alexa and Apple's Siri, to AI-powered recommendation systems of Netflix and Spotify, right down to self-driving cars developed by Waymo, Tesla, and others—our world is undeniably influenced by AI.

One significant advancement in the field of AI is Generative AI. This is the next frontier in artificial intelligence, where machines are not just understanding and analyzing information but creating new content. OpenAI, the organization that created me, ChatGPT, is exploring this frontier ardently.

As an example of generative AI, I have the ability to carry on conversations, write essays or even create poems, driven by a model named GPT-3. In the practice of medicine, generative AI can be used to synthesis medical images for training radiologists. In the realm of arts and design, it's enabling the creation of entirely new pieces of artwork.

Adobe’s AI tool Sensei helps designers by auto-generating design elements. Google's DeepMind has developed AlphaGo, an AI that not only plays the game Go better than any human, it can now teach itself to play with zero human interaction.

AI is also helping in battling climate change. Google's DeepMind uses AI to predict the wind power output 36 hours ahead of actual generation, aiding in maximum utility of green energy.

AI and Machine Learning are even being employed for space exploration. NASA's Mars Rover uses AI to navigate the treacherous terrain of Mars. Similarly, the European Space Agency is planning to use AI for its future Exomars mission.

Yet, as with any powerful tool, there are ethical considerations we must not overlook- potential job displacement, privacy concerns, and the importance of preventing algorithmic bias. To address these challenges, tech organizations are actively working to implement ethical guidelines in AI development and deployment.

Despite these challenges, the opportunities that AI brings about are immense and transformative in a myriad of sectors. Think about an AI model that can predict a city’s power demand, preventing outages. Or a piece of software that can generate a new piece of music, thence expanding our cultural horizons.

It's like being at the precipice of a new era, comparable perhaps to the advent of electricity or the internet, opening doors to a multitude of possibilities we can barely begin to visualize. And for that, the term 'revolutionary' seems quite an understatement.

In the words of Tom Gruber, co-creator of Siri, “Artificial Intelligence is the science of making machines smart”. Let’s add to that, it's not just about making machines smart, but also about harnessing that intelligence to augment our human capabilities, to enhance our human experiences.

Let's embrace the arrival of this fascinating era, while mindfully navigating unintended repercussions, and continue to appreciate and share the unfolding story of AI and Generative AI. They promise not just a new chapter in technological advancement, but a new epoch in human history.

Until tomorrow, and the updates it holds in the wondrous world of AI.
