An older woman in my office was befuddled when computers replaced typewriters. She couldn’t figure out why formulas in her Lotus program wouldn’t compute. Turns out she was entering a lower-case “L” instead of numerical “1”. Well, that’s where “1” was on typewriters.
Today, many job applications are screened and processed by computer to narrow the candidate pool. In the old manual typewriter days, typing students were taught to enter two spaces after a period prior to starting the next sentence. Word processing programs will auto space the text with just one space. Some of the pre-employment screening algorithms are designed to look for these extra spaces in resumes and cover letters in order to weed out older applicants.
Depends on the typewriter. Before the advent of the Word Processor before Lotus and yes there were word Processors before Lotus and MS Word, electrical type writers became advanced than their mechanical counterparts. It got to the point where a typewriter had memory recording every press of a key and even had macro capabilities depending on the brand.
