Every processor we know today contains tens of thousands of transistors, which consist of logic gates. It’s worth noting that Google is developing technology that would be able to assemble such a processor in a few hours, because today it takes several years. Let’s take a look at what that would change.
Basic logic gates
Processors can do different jobs. They do them because of zeros and ones. It is the logic gates, which include the basic ones, that help them to solve even complex tasks:
AND logic gate (conjugator)
A gate with two inputs and one output that is a logic one only when both inputs are logic ones.
Logic gate OR (disjunction)
A gate with two inputs and one output that is a logic one only when at least one of the inputs is a logic one.
Logic gate NOT (inverter)
A gate that forms a negation, changing the input value of a logic signal to its opposite.
The combination of the AND and NOT gates results in a NAND gate, where the output is exactly the opposite of the AND, i.e. the logic one will always be the logic one, except when both inputs are logic one. The beauty of NAND is that you can fold it into any basic logic gate, so in the real world this gate is mainly used after the definition of everything. These gates are then used to compose transistors and eventually processors.
A few hours
Today, these chips are not designed by hand, as this would take too long. Nowadays IP cores are used for design. But there is a need for a new design process, one that would be able to design a new chip within 6 hours. That’s where artificial intelligence (AI) comes in. Its very development is already accelerating and Google is working on AI that should reduce chip design from a few years (currently 2-5 years) to a few hours, so in theory we should have new chips very quickly and very often.

There is already an experiment where AI, after feeding the necessary data, was able to design a chip in 6 hours, whereas a human would need several weeks. So it is more than certain that if we want to push digital development further forward, we will be putting it in the hands of AI.
