The document discusses asynchronous chips, which operate without a central clock. It notes problems with synchronous chips like speed limitations and wasted energy from distributing a global clock. Asynchronous chips can operate at different speeds in different parts and exchange data using handshake signals only when needed. While asynchronous chips could reduce power consumption and noise, challenges remain in interfacing them with synchronous devices and a lack of expertise and tools for asynchronous design. The conclusion states that clocks will face difficulties in future complex chip designs due to noise, power and costs, making asynchronous approaches more appealing.
