No. English has used else to mean "otherwise" since before computers came along. Wiktionary offers this quote from Call of the Wild (1903):

"He had never seen dogs fight as these wolfish creatures fought, and his first experience taught him an unforgetable lesson. It is true, it was a vicarious experience, else he would not have lived to profit by it."

There's also "or else", as made famous in crime dramas: "Meet me by the docks at midnight. Bring the money. Come alone. No cops... or else!" But in other usage it can of course be followed by something. "He had to get to work on time, or else he might be fired."
