High technology (high tech or high-tech), also known as advanced technology (advanced tech) or exotechnology,[1][failed verification] is technology that is at the cutting edge: the highest form of technology available.[2] It can be defined as either the most complex or the newest technology on the market.[3] The opposite of high tech is low technology, referring to simple, often traditional or mechanical technology; for example, a slide rule is a low-tech calculating device.[4][5][6] When high tech becomes old, it becomes low tech, for example vacuum tube electronics. Further, high tech is related to the concept of mid-tech, that is a balance between the two opposite extreme qualities of low-tech and high tech. Mid-tech could be understood as an inclusive middle that combines the efficiency and versatility of digital/automated technology with low-tech's potential for autonomy and resilience.[7]
Startups working on high technologies (or developing new high technologies) are sometimes referred to as deep tech; the term may also refer to disruptive innovations or those based on scientific discoveries.[8]
High tech, as opposed to high-touch, may refer to self-service experiences that do not require human interaction.[9]
