Final answer:
The idea of machine intelligence was introduced earlier than the 1970s with the development of experimental computers in the 1940s.
Step-by-step explanation:
The idea that a machine could be intelligent was actually introduced earlier than the 1970s, when the first digital computer was introduced.
Experimental computers were first developed in the 1940s and became commercially important in the 1950s. However, it wasn't until the mid-20th century that the invention of the transistor and the development of minicomputers made computing technology more widely available.
So, the statement that the idea of machine intelligence was first introduced in the 1970s with the introduction of the first digital computer is false.
