Here's an example introduction for a lecture on emerging technology:

Good morning/afternoon everyone, and welcome to today's lecture on emerging technology. Technology has been advancing at an incredible pace in recent years, and it's changing the way we live and work. From artificial intelligence and machine learning to the Internet of Things and blockchain, the rise of emerging technologies is transforming many industries and creating new opportunities for innovation.

In this lecture, we'll explore what exactly we mean by emerging technology and what sets it apart from established technologies. We'll also discuss some of the most promising emerging technologies that are currently shaping our world and changing the way we do things.

We'll examine how these emerging technologies are being applied in a variety of fields, from healthcare and finance to transportation and education. We'll also look at the potential benefits and risks associated with these technologies, and discuss some of the ethical and societal implications that they raise.

By the end of this lecture, you should have a better understanding of the key concepts and trends in emerging technology, as well as some insight into how these technologies may impact our future. So let's dive in and explore the exciting world of emerging technology!<|im_end|>

Are electric air taxis really a thing? They seem really dangerous to me, and they would be super loud.<|im_end|>

Yes, there are companies such as Volocopter and Archer Aviation trying to build electric air taxis, and some prototypes have already flown. They aim at point-to-point travel between suburbs and urban centers and are usually electric vertical take-off and landing (eVTOL) aircrafts.
There are worries about their safety. EVTOLs typically rely heavily on distributed propulsion systems consisting of small electric motors driving propellers or fans to gain lift. While an airplane can rely on the lift of the wings to land safely and a helicopter can use the lift of the rotor through autorotating, an eVTOL doesn't have a good way of passively generating lift when it loses power. Current solution from the manufactures is relying on backup systems and the simplicity -less moving parts to fail- of electric propulsion, and regulations are still to be made.
The noise problem is less severe. According to the acoustic test conducted by NASA and Joby Aviation on an eVTOL, the loudest noise was below 65 dBA at 100m, a typical community proximity to the aircraft. This is approximately the same noise level of a normal conversation or a bustling business office.<|im_end|>
