If you’re waiting for a new iPhone powerful enough to do everything, Doraemon might have already brought the answer from the 22nd century. In the world of this robotic cat, there are plenty of gadgets so handy and versatile that if they existed in real life, smartphones might only be backup devices. So, if we put them side by side, which Doraemon gadgets could actually “replace” the iPhone?
Future Encyclopedia Device
In many episodes, Doraemon uses devices like a “future lookup machine” that instantly answers any question, from academic knowledge to everyday information. Compared to the iPhone, which requires internet and app searches, these gadgets work almost instantly without complicated steps.
The key difference is that the iPhone is a tool, while Doraemon’s gadgets act like an “auxiliary brain.” Users don’t need to know how to search, they just ask. If real-world technology reached this level, smartphones wouldn’t just be information access devices but would give way to systems that understand and respond like humans.
Memory Bread: “Copy and paste” knowledge directly into your brain
One of the most famous gadgets has to be the memory bread. Just press the bread onto a book and eat it, and you instantly remember all the content. If it were real, this would be a nightmare for every learning app on the iPhone.
Today, smartphones support learning through videos, apps, and AI but still rely on natural human memory. Memory bread skips this entire process. However, it raises an interesting question: if learning becomes too easy, do people truly understand knowledge or just store it?
Anywhere Door: Replacing maps, ride-hailing, and travel
While the iPhone helps you book rides, check maps, and find directions, Doraemon’s Anywhere Door is much simpler, open the door and you’re there. No need for Google Maps, ride apps, or plane tickets.
Compared to smartphones, this is not just a convenience upgrade but a giant leap in how humans travel. When distance no longer matters, many services supported by the iPhone, from tourism to logistics, could become obsolete.
Weather-Changing Machine: When forecasts become unnecessary
The iPhone can provide fairly accurate weather forecasts but only to help you prepare. Doraemon’s weather-changing gadget lets you alter the climate at will.
If this technology existed, people wouldn’t rely on forecasts but would directly control the weather. Weather apps, disaster alerts, and even many meteorology-related industries would have to redefine their roles.
Comparing the iPhone to Doraemon’s gadgets is like placing today’s technology next to a future far beyond imagination. Smartphones, no matter how smart, remain tools that assist humans. Meanwhile, Doraemon’s gadgets almost replace many human functions, from memory and travel to decision-making.
So, if you ask which gadget could replace the iPhone, the answer is probably not just one but many. Yet from another perspective, today’s iPhones and tech devices are the first steps bringing humanity closer to Doraemon’s world, where what once seemed like science fiction could gradually become reality.
