Technological lock-in
Technological lock-in occurs when a system becomes dependent on a specific technology, standard, or platform to the point that switching costs exceed the benefits of adopting a superior alternative. The phenomenon is not merely economic; it is structural. Once a technology achieves sufficient adoption, the network of complementary products, trained users, accumulated data, and institutional processes that surround it creates a self-reinforcing feedback loop that resists displacement even when objectively better alternatives exist.
The classic examples include the QWERTY keyboard layout, the VHS video format, and the dominance of the x86 architecture in personal computing. But the most consequential cases of lock-in involve infrastructure: the AT&T Bell System's prohibition on non-Bell equipment, the Microsoft Windows ecosystem's software compatibility, and the contemporary platform economies where data accumulation creates switching costs that no competitor can overcome.
From a systems perspective, technological lock-in is an attractor in the dynamics of technology adoption. The basin of attraction is defined by network effects, learning curves, and complementary investments. Once a system enters the basin, escaping requires either catastrophic disruption or regulatory intervention. Market forces alone are insufficient because the market mechanism is itself captured by the lock-in.
