Overall, it played a crucial role in the industrialization and economic growth of the late 19th and early 20th centuries.

The identity of the first Pakhtoon is not definitively established, as the term "Pakhtoon" refers to a group of ethnic people rather than a single individual. Historically, Pakhtoons, also known as Pashtuns, trace their ancestry to various tribes and are believed to be descended from the ancient Indo-Aryan tribes. Legends and historical accounts often mention figures like Qais Abdur Rashid as a mythical ancestor of the Pashtun people, but these origins are steeped in folklore rather than verifiable history.

Key inventions that facilitated the outward growth of cities include the steam engine, which powered trains and allowed for efficient transportation, and the automobile, which enabled people to live farther from their workplaces. Additionally, the development of the electric streetcar expanded urban boundaries by connecting suburban areas to city centers. Advances in construction techniques, like the elevator and reinforced concrete, also enabled taller buildings, accommodating more residents and businesses in expanding urban areas.

Good communication on a printing press enhances collaboration among team members, leading to improved workflow and productivity. It ensures that everyone is aligned on project specifications, timelines, and quality standards, reducing the chances of errors and reprints.
