Hello everyone, I'm here to tell you a bit more about the engrossing world of artificial intelligence, or AI, with special emphasis on generative AI.

AI is a sweeping domain of computer science that focuses on the creation of intelligent machines that can replicate human intelligence. Its roots can be traced back to classical philosophers who attempted to describe human thinking as a symbolic system, laying the groundwork for what we now refer to as symbolic AI. The field has witnessed remarkable evolution in the past few decades, with advancements in machine learning, deep learning and, more recently, a subset known as generative AI.

When we talk about generative AI, we're mainly talking about systems that can generate new data that could, in principle, be indistinguishable from real data. OpenAI's GPT-3, the program creating this message, is a prime example. It generates complete paragraphs of text that can mimic the style and tone of a human author.

Chatbots powered by AI have also seen a significant uptick. These bots can engage with customers, respond to queries, set up appointments - tasks that were previously handled by humans. Leading businesses like Amazon, Microsoft, and IBM have leveraged these technologies to provide more efficient services.

Spearheading the field of AI in businesses are AI-as-a-service platforms like Google's Cloud AutoML, IBM's Watson, and Amazon's SageMaker, which provide pre-trained models to developers. This allows even small businesses to leverage AI without having to worry about the complexities of engineering or tuning machine learning models themselves.

One area where AI is making churning waves is in health care. An example is Google's DeepMind's AlphaFold tool that predicts the 3D structure of a protein based on its amino acid sequence. This technology has immense implications on drug discovery, and understanding diseases.

Then there's Fetch.AI. At its core, Fetch.AI aims at connecting everything to everything, a concept of interoperability very vital to the development of the smart cities of the future. It allows devices to communicate in meaningful ways without human intervention by merging machine learning, AI and blockchain technologies.

Artificial intelligence is also increasingly contributing to saving our environment, an example being Microsoft’s AI for Earth initiative. It provides AI tools and skills for various organizations to tackle global environmental challenges related to agriculture, water, biodiversity, and climate change.

Yet, amid all these advancements, we also heed concerns. Ethical concerns around AI decision-making and privacy do need addressing. Hence, organizations like the Partnership on AI, founded by Amazon, Apple, Google, IBM, Microsoft, and Facebook are fostering cooperation and formulating best practices on AI technologies.

There's far more to AI than can be summarized within these words. AI isn't an idea of the future, rather it's a present reality transforming various industries. The next wave of AI, with deepfake videos, virtual reality, and autonomous systems, is going to be even more fascinating. Remember, we're all part of this journey and each one of us has a role to play in shaping this exciting future. Explore, engage and enjoy the world of AI.
