Some of the hardware behind modern communication may go unnoticed for a long time before it is formally honoured.

The Nobel press release said this year's Nobel Prize in Physics is awarded for two scientific achievements that have helped to shape the foundations of today’s networked societies. It gave the prize amount as SEK 10 million, with Kao awarded one half and Boyle and Smith sharing the other half.

How Foundational Hardware Matures Over Decades

According to the release, in 1966, Charles K. Kao made a discovery that led to a breakthrough in fiber optics. The release stated the first ultrapure fiber was successfully fabricated just four years later, in 1970. It also stated that in 1969 Willard S. Boyle and George E. Smith invented the first successful imaging technology using a digital sensor, a CCD (Charge-Coupled Device).

The gap of about four decades between this work and the prize invites a question about how technologies mature. One reading is that components such as sensors that capture light and fibers that carry it may need to become widespread before their weight is fully judged. Together, the two achievements also suggest a pairing: a way to turn images into signals, and a way to move light over long distances.

In general, hardware may take time to spread, since it has to be made, shipped and installed. Once in place, it might fade into the background, while people notice mainly the services built on it. If recognition waits for those wider effects to show, it may simply take a long time.

For people building new systems, this may offer some patience: the most basic layers of a technology might be acknowledged only long after they were first made. Perhaps foundational work is often recognized late.
