The strongest links are not all the same: Motorola said its 1996 StarTAC drew inspiration from the communicator, while tricorder-like DNA analysis and virtual reality are narrower analogies, not replicas of fictional devices.
The original Star Trek premiered on September 8, 1966, and Star Trek: The Next Generation began in 1987, according to NASA’s franchise history. Here are five useful comparisons—and what today’s technology can actually do.

1. The communicator anticipated the mobile phone’s form
Original-series characters flip open compact communicators to speak with people at a distance. The closest familiar counterpart is the mobile phone, particularly the flip-phone design. HISTORY reports that Motorola’s StarTAC, released in 1996, drew inspiration from the Star Trek communicator. That is a specific design influence, not evidence that the show invented mobile communication: Motorola had released a commercially available handheld cell phone in 1983, as the same HISTORY retrospective notes.

A communicator is principally a voice device; smartphones add functions such as email, web access, directions, and photography. The official Star Trek technology feature makes that distinction while describing the communicator’s influence on early flip phones.

2. The PADD anticipated the tablet computer
The Next Generation introduced handheld Personal Access Display Devices, or PADDs: thin screens used to read and interact with information. Their shape and everyday role are readily recognizable in tablet computers. Apple launched the iPad in 2010, and HISTORY notes that Apple co-founder Steve Wozniak said the iPad reminded him of the fictional device.
That is a resemblance and a reported recognition, not proof that the series caused tablet development. Scientific American includes tablets among The Next Generation’s apparent technology “bullseyes,” but a fictional design anticipating a category is different from establishing its origin. See the HISTORY overview and Scientific American’s comparison.
3. Tricorder-like tools can identify microbes, not diagnose anything
Dr. Leonard McCoy’s tricorder scans a patient and supplies medical information in moments. The real-world parallel is much narrower: a U.S. Department of State feature describes NASA-related work aboard the International Space Station that uses handheld tools to identify microbes. A miniPCR device makes copies of targeted microbial DNA; a MinION sequences the DNA. Together, they provide a task-specific sensing and analysis workflow, not a single general-purpose medical scanner.
NASA microbiologist Sarah Wallace of Johnson Space Center described the achievement this way: “DNA sequencing in real time on the space station is a huge leap forward.” The State Department feature says NASA is working to automate and speed sample preparation. It does not establish that the system can instantly diagnose arbitrary illnesses in a person.

- Brand New in box. The product ships with all relevant accessories
The same feature discusses hopes for gene sequencing at a lunar base and a closer tricorder-like device on a Mars mission in the 2040s. Those are aspirations, not scheduled outcomes or capabilities available today.
4. The ship’s computer anticipated voice assistants
Star Trek characters ask the ship’s computer questions aloud and receive spoken responses. In Star Trek IV: The Voyage Home, Montgomery Scott is surprised when a desktop computer does not respond to voice commands. That familiar call-and-response interface has a present-day analogue in virtual assistants and conversational interfaces, as both HISTORY and Scientific American discuss.

The comparison is about interacting by voice, not equivalent intelligence. The fictional ship’s computer can answer an extraordinarily broad range of questions and operate ship systems; current assistants do not thereby become all-knowing computers. They also rely on software, devices, and often network services rather than functioning as a single self-sufficient intelligence.
5. The holodeck anticipated the idea of virtual reality
A holodeck creates an interactive simulated world that characters can enter. Virtual-reality headsets similarly place users inside computer-generated environments, making VR a useful conceptual analogue. Scientific American draws that comparison, but today’s VR is not the holodeck: the sources do not establish a responsive physical environment that can reproduce the fictional room’s full sensory and interactive experience.

These examples represent different kinds of connection. The communicator has a reported design influence on a specific phone; the PADD is a strong visual and everyday-use comparison; voice assistants share an interface idea; and tricorder research and VR resemble particular parts of fictional capabilities. Treating all five as inventions caused by the show would overstate the evidence.
Astrophysicist Ethan Siegel offered a broader interpretation in HISTORY: “I would say that one of the really important things that ‘Star Trek’ gave us is a vision for technology solving some very human problems that we’ve had for a very long period of time.” That describes an influence on how people imagine technology, not proof that any specific device originated in the series. For additional context, NASA’s history of the franchise dates the original premiere to 1966 and The Next Generation to 1987.
Two famous technologies that remain science-fiction contrasts
Replicators and 3D printers
Three-dimensional printers can form objects from materials such as plastic, but that is not the same as assembling matter at the molecular level or producing any meal or object on demand. The official Star Trek technology feature uses the distinction to explain why a 3D printer is not a replicator.
Transporters and quantum teleportation
Transporters remain fictional, and Scientific American describes teleporters as unrealized. Quantum information teleportation transfers quantum information or a state; it does not beam people or bulk matter through space. The franchise’s technology feature and Scientific American’s scorecard provide useful context for keeping the comparison precise.
Why the comparisons still matter
Star Trek’s most persuasive technology parallels are not demonstrations that television predicted an inevitable future. They show how memorable fictional designs can make emerging possibilities legible: a communicator suggests portable connection, a PADD suggests a screen you carry, and a voice-querying computer suggests a different way to interact with information. The real devices have their own histories and constraints, but the comparisons help explain why these ideas remain part of the series’ cultural legacy.
