The AI Translator
Johnston has earned the nickname "The AI Translator" for his unique ability to bridge the gap between technical AI capabilities and practical business applications. Unlike many in the AI space, he doesn't dumb things down — he makes them clear.
"Most AI education falls into two camps: too technical for business owners, or so simplified it's useless. I sit in the middle — I translate AI into business outcomes without losing the nuance that makes it actually work."
