On the most fundamental level, a CPU and human brain essentially function in the same way: electrical signals. A CPU's transistor is analogous to a neuron in the brain. The earliest evolved brains were essentially a cluster of nerve cells which then grew in number and size over millions of years, and as this happened sentience and then eventually consciousness gradually emerged.
Our CPUs have been doubling in transistor count every two years for decades now, although this has slowed down in recent years and may eventually stop at 5-nanometre nodes (although Intel has stated that CPUs may reach 100 billion transistors in 2026, equivalent to the number of neurons in the brain[1]). It's certainly possible that CPUs could eventually "think for themselves" and begin making decisions without human input, although whether or not that qualifies as sentience is unknown, as is the case with "primitive" life.
