It's unfair to dismiss and simplify this technology when it only just started reaching critical mass ~2 years ago. Looking at history, transformative technologies rarely show immediate productivity gains. The internet took nearly a decade from the early 1990s before we saw clear economic impact. Electricity needed 30 years (1890s-1920s) to significantly transform industrial productivity, as factories had to completely redesign their operations. Personal computers were around since the late 1970s, but their productivity impact wasn't measurable until the late 1980s/early 1990s. Major technological shifts require time for society to develop optimal use cases, build supporting infrastructure, and adapt workflows
