Michael Dell, founder of Dell Technologies, shared a one-page financial statement from 1984 that he said changed his life. The document, from his dorm-room computer business, showed significant revenue and earnings, convincing his parents that he should not return to college. That business, which began by selling PC upgrade packages, later adopted a direct-to-consumer model for custom-built computers. Today, Dell Technologies builds infrastructure for artificial intelligence.
In a separate scientific development, researchers have found evidence of lichen-like life dating back 600 million years, which may push back the origins of fungal-algal partnerships. Symbiosis, a mutually beneficial or ambivalent relationship between two organisms, is central to this discovery.
