1. Personal Computers: Electronic computers, as we know them today, were not in existence during the early 20th century. Personal computers became widely available decades after the Titanic sank.
2. Smartphones and Tablets: Mobile devices like smartphones and tablets were non-existent during the early 1900s. Cell phones and mobile communication technology were still in their early stages.
3. Digital Cameras: Digital photography and digital cameras had not been invented yet, so all photography on board the Titanic was done with traditional film cameras.
4. Internet and Wi-Fi: The Internet, as we know it today, did not exist until the late 1980s. Access to the Internet and wireless Wi-Fi connections were unimaginable in 1912.
5. Televisions: Electronic television broadcasting did not begin until the 1920s, making televisions completely unknown to society at the time of the Titanic's journey.
6. Electric Toothbrushes: Electric toothbrushes were not introduced until the 1930s, so the passengers and crew of the Titanic used traditional manual toothbrushes.
7. Electronic Devices: Various modern electronic devices we take for granted, such as laptops, electronic game consoles, MP3 players, and so on, were far beyond the technological advancements of that time.
8. Wireless Communications: Although the early concepts of radio communication existed, practical long-range wireless communications, as we know them today, were still several years away in the 1910s.
9. Digital Audio Players: Technology for playing digital audio files (such as iPods) was several decades away from being developed. Passengers on the Titanic listened to music using phonographs or live musicians.
10. Video Conferencing: Real-time video communication technology was not introduced until much later, so passengers on the Titanic had no way of making video calls or connecting with people remotely.
These examples highlight the significant advancements in technology that have taken place since the early 20th century, showcasing the evolution and progress that society has made in just over a hundred years.
