The Line: A futuristic Saudi city made entirely of skyscrapers

The Line is a proposed linear city in Saudi Arabia that would stretch for 170 kilometers (106 miles) and be home to up to nine million people. The city would be built on a narrow strip of land along the Red Sea coast and would be powered by renewable energy.
The Line is the centerpiece of Saudi Arabia's Vision 2030 plan, which aims to diversify the country's economy and reduce its dependence on oil. The city is expected to cost up to $1 trillion to build and would be completed in phases over the next decade.
The Line has been met with mixed reactions. Some have praised the project as a bold and ambitious vision for the future, while others have raised concerns about its feasibility and environmental impact.
Here are some of the features that are planned for The Line:

No cars: The city would be car-free, with residents and visitors getting around on foot, on bicycles, or via public transit.
Vertical parks: The city would feature vertical parks and green spaces throughout its length.
Smart technology: The city would be powered by the latest smart technology, including AI and robotics.
Sustainability: The city would be built to be sustainable, with a focus on renewable energy and water conservation.
Innovation hub: The city would be a hub for innovation and technology, with a focus on research and development.

The Line is a major project that has the potential to transform Saudi Arabia and the region. It is a bold and ambitious vision for the future, but it remains to be seen whether it can be realized.
Here are some of the challenges that the project faces:

Cost: The city is expected to cost up to $1 trillion to build, which is a significant financial challenge.
Feasibility: The city would be built on a narrow strip of land along the Red Sea coast, which could pose engineering challenges.
Environmental impact: The city's construction and operation could have a significant environmental impact.
Public acceptance: The city would be a major change from traditional urban planning and it is unclear how the public will react to it.

Despite the challenges, The Line has the potential to be a major success. If it can be built, it would be a global landmark and a showcase for Saudi Arabia's ambition and innovation.
