The IBM Think 2018 conference is all about the latest from Big Blue, and one such project comes in a very small package-- a computer the size of a grain of rock salt packing the power of a 1990 x86 chip.
The extra-tiny (1 x 1mm!) computer is part of the "5 in 5," a collection of inventions and technologies IBM Research says "could change our lives in the next 5 years." It consists of a few hundred thousand transistors, an unspecified amount of RAM, a solar cell and an LED-based communications module. IBM adds it should be very cheap to produce, at around 10c apiece.
