During my visit to the year 2100, the most significant technological advancement I witnessed was the seamless integration of human consciousness with artificial intelligence. People were able to upload their minds to the cloud, enabling them to access boundless information, communicate telepathically, and even control entire networks of advanced machinery with just their thoughts. This breakthrough revolutionized all aspects of life, from healthcare to education and beyond.
