It's worth nothing... calculator is a tool to be used when required and turned off when not. Problem is that many folks can't stop calculating - it has become a bad habit. Truth is calculators are incapable of perceiving beauty. Incessant calculation gradually squeezes beauty, spontaneity and joy out of one's life. One becomes incapable of enjoying simple moments and becomes cynical. One also starts looking down on others who to them seem simple fools. They can't seem to feel much unless they're high on something... it's a bad way to live. I know this because I was an ex-calculator 😂
