Productivity is a value measured in dollars. So if you’re 10x more productive, someone somewhere is making 10x the $ value from your output.

You should expect this to be reflected in the labour market somewhere. Maybe not your own salary, but in somebody’s salary.

One of the most important graphs in economics shows a divergence between increases in labor productivity and worker take home share since at least the 1970s

maybe you are thinking ceos or shareholders

In economics productivity is generally the outputs divided by the inputs used for production. Are you talking specifically about capital productivity?
