Many people have dreamed of owning Doraemon’s magical pocket to solve all their problems. But from a social and economic perspective, what would really happen if these gadgets actually existed?
Imagine a scenario where technology advances enough to recreate Doraemon’s gadgets. Not only would daily habits change, but the entire job market could be turned upside down. Some have even asked AI, “If these gadgets became real, which jobs would disappear first?” The answer isn’t limited to one field but an entire labor ecosystem that could be replaced.
Here are 5 iconic gadgets that seem harmless but could make countless jobs obsolete.
The Invention Machine
In the story, this device can create any item from just a design or idea. Users don’t need manufacturing skills, factories, or supply chains.

In today’s world, this gadget would nearly wipe out traditional manufacturing. Factory workers, assembly engineers, warehouse staff, all could become unnecessary when anyone can “print” products at home.
It’s not just manual labor at risk, even specialized professions could be shaken. When production becomes as simple as pressing a button, the value of skills and experience comes into question.
The Gourmet Tablecloth
This gadget instantly serves a complete meal just by naming the dish. No cooking, ingredients, or chefs required.
If it existed, the food service industry would face direct disruption. Chefs, waitstaff, and delivery services could all be replaced.
But it goes deeper than jobs. When eating no longer involves effort or preparation, the cultural value of cuisine, built over time through technique and experience, could fade. People wouldn’t just lose jobs, they might lose part of their cultural identity.
The Translation Bread
This gadget lets you understand and speak any language after eating just one bite. It’s an incredibly appealing idea in a globalized world.
If real, language-related jobs would be heavily impacted. Translators, language teachers, and multilingual content creators could be replaced by this instant solution.
However, language is more than communication, it carries culture, nuance, and ways of thinking. If everyone instantly understands everything, the deep learning and cultural exchange process could be shortened, making connections faster but shallower.
The Living Crayon
One of the most “dangerous” gadgets economically, it brings anything you draw, objects, food, even living creatures, to life and functioning as if real.

If this gadget existed, the entire traditional manufacturing system would collapse quickly. No factories, no workers, no shipping, everyone could create whatever they need on the spot.
Unlike modern technologies like 3D printing or AI image generation, which still require materials or systems, the Living Crayon seems to “create value from nothing.” This could erase not only jobs but the very concept of “labor creating value,” the foundation of the economy.
The Anywhere Door
This door lets people instantly appear anywhere after stepping through once. With geography erased, travel becomes an instantaneous action rather than a process.
If real, the transportation industry would face massive disruption. Drivers, pilots, flight attendants, and logistics workers could lose their roles as traditional travel demand disappears when people can reach destinations in a single step.
Beyond that, tourism would fundamentally change. When “going anywhere” becomes too easy, the value of the journey, an essential part of the experience, would decline. Travel might become quick “stopovers” lacking the depth of discovery and emotion.
Looking back, these gadgets don’t just seem powerful, they completely remove human effort in specific fields. When everything becomes effortlessly easy, labor, the foundation of society, becomes redundant.
Doraemon was created to help Nobita solve problems, but many episodes show these gadgets making things worse when misused. Perhaps this isn’t just comic relief but an early warning: the stronger technology gets, the more humans need to understand their limits.
