If/when we take sane steps to address climate change long-distance freight (save for some perishables) will transition from trucks to rail.
Transport from railheads to destination will be by electric trucks that are better suited to shorter routes. There will probably be no huge change in the number of jobs and truckers will spend most nights at home. Another big transition will be a shift from regional air travel to high-speed rail.
There will be no socialism unless we let climate change get to the catastrophic stage. These decisions will occur because of the economics as the article suggests. As that will not occur nearly fast enough to prevent catastrophes government likely will act to speed the process but it will not be socialism but rather democratic socialism in which elected representatives will do the jobs they are elected for and serve and protect citizens.
