1. 3-D Printing

3D printing or additive manufacturing is the construction of a three-dimensional object from a CAD model or a digital 3D model. It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, with material being added together, typically layer by layer.

2. TikTok

TikTok, known in China as Douyin, is a video-focused social networking service owned by Chinese company ByteDance Ltd. It hosts a variety of short-form user videos, from genres like pranks, stunts, tricks, jokes, dance, and entertainment with durations from 15 seconds to ten minutes.

3. Facial Recognition

A facial recognition system is a technology capable of matching a human face from a digital image or a video frame against a database of faces. Such a system is typically employed to authenticate users through ID verification services, and works by pinpointing and measuring facial features from a given image.

4. ChatGPT

ChatGPT is an artificial intelligence chatbot developed by OpenAI and released in November 2022. It is built on top of OpenAI's GPT-3.5 and GPT-4 foundational large language models and has been fine-tuned using both supervised and reinforcement learning techniques.

5. Delivery Drones

A delivery drone is an unmanned aerial vehicle (UAV) designed to deliver packages to consumers in the final stage of delivery. Typically equipped with 4-8 propellers, rechargeable batteries, and the capacity for lightweight containers, these drones can operate autonomously with AI or be remotely controlled.

6. Self-Driving Technology

A self-driving car, also known as an autonomous vehicle (AV), autonomous car, driverless car, or robotic car (robo-car), is a car incorporating vehicular automation, that is, a ground vehicle that is capable of sensing its environment and moving safely with little or no human input.

Self-driving cars combine a variety of sensors to perceive their surroundings, such as thermographic cameras, radar, lidar, sonar, GPS, odometry and inertial measurement units. Advanced control systems interpret sensory information to identify appropriate navigation paths, as well as obstacles and relevant signage.

7. Military Drones

Swarm drones use machine and artificial intelligence to coordinate multiple UAVs into a single networked system for communication, reconnaissance, and attacking targets. This concept involves deploying numerous UAVs equipped with sensors, weapons, and communication tools to gather data, create a detailed battle picture, and relay information to multiple users in real-time.

8. CRISPR

CRISPR (clustered regularly interspaced short palindromic repeats) is a family of DNA sequences in prokaryotes like bacteria and archaea, derived from bacteriophage DNA fragments from past infections. These sequences help detect and destroy similar bacteriophage DNA in future infections, playing a crucial role in the prokaryotes' antiviral defense system and providing acquired immunity. This editing process has a wide variety of applications including basic biological research, development of biotechnological products, and treatment of diseases.

9. Health Tracking

“On August 31, 2023, Fitbit and Google came under fire (again) for how the tech giant has been treating its users' potentially sensitive health data. 

The best Fitbits are terrific devices that monitor heart rate, sleep, calories burned, workouts, menstrual cycle patterns, and more. But for a long time, concerns have been raised about how this data is being used, especially whether it’s being used to complement Google’s massive data-driven targeted advertising operation.

So where is all your data going? Unfortunately, there’s no easy answer: Google and Fitbit have remained tight-lipped, insisting they are using data responsibly and only sharing it for necessary processing purposes, or with user consent. Other parties have attempted to dig into how Fitbit health data is being used or take Google to task over its lack of transparency, with varying degrees of success.”
