While Paul and Claire's points on space satellites and medical progress are valid, I believe that the most pivotal invention in the last two centuries is the internet. The internet has revolutionized global communication, enabling instantaneous connections across vast distances. For instance, applications such as Skype and WeChat have become integral to our daily lives, allowing us to engage in video chats at any time. The recent pandemic further highlighted the importance of the internet; countless individuals were confined to their homes, yet business operations and project developments continued seamlessly through online meetings.
