“We didn’t have to teach you how to use a pen, why do we need to teach you how to use a computer?”
In the early 1980’s, I was rather shocked to hear a manager exclaim that employees needed to figure out how to use computers to do their jobs. There were no training guides, and only a few classes available, with most being devoted to coding. The manager, at that time, did not use computers, but dreamed of the potential productivity gains promised by the marketers.
Fast forward. In 2019, most households now own at least one computer. Many use computers for entertainment or basic communications, but not necessarily business applications such as word processing, spreadsheets, and Internet. Many people use their phones and other mobile devices to access the Internet. Even then, approximately 10 percent of the US population do not use the Internet at all. 
Yet, most jobs today involve interacting with technology on a regular basis and there is a certain amount of people who are being literally ‘left behind’ due to the lack of skills and knowledge. It involves more than just jobs, but social interaction opportunities, education and continued learning, resource access, and making everyday tasks easier. 
It is like driving a car, you don’t need to know how to repair it to drive it well. But just because you have the key to the car doesn’t mean you know how to drive it.
Any truly gifted crafter, be it a tradesperson, artist, musician, builder, etc., well understands their tools: when and how to use them, and how to take care of them. But...i is like driving a car, you don't need to know how to repair it to drive it well. But just because you have the key to the cr doesn't mean you know how to drive it.
Many companies are expecting this of all modern workforce workers. They expect them to know a bit about the application software (such as word processing, spreadsheet, electronic mail, and basic Internet searches) and when to use each. People who understand these basics can qualify for better and higher paying jobs. These basic applications may be required for taking orders, communicating with other co-workers, accessing information, and completing a timecard. Many companies are now doing their hiring using automated systems, which requires a certain amount of Internet suave.
People that don’t know these things may not be employable. A recent example occurred in Oahu, Hawaii when local unemployment processes were assessed. Fully 60 percent of job-seekers did not have adequate computer skills, access to the Internet, or navigational skills to use the online hiring system without assistance. 
Technological illiteracy and technophobia is no longer a sustainable for many modern careers. Both young and more mature workers may demonstrate this in different ways. Mature workers, often the dependable workhorses, have the highest unemployment rates, and often need to bring their skills up-to-date or develop the basics. Younger workers may have more exposure to certain computer uses, but may lack both soft and hard skills needed in business.
“Entire sectors of the U.S. economy have no place for workers who do not at least have the basic digital skills to undertake tasks like word processing and maintaining spreadsheets...” Don’t get left behind.
