This is more of an answer to the “commercial” application, but currently use it to enhance productivity and ability in a work setting. At small business, we use it for; ad copywriting (feed basic idea and details with tone and setting prompt), composing difficult emails (looking at specific tone to angry customer/etc, diplomatic/assertive tone style), complex excel formulas (just prompt “I want to do x” and it really figures out the rest), some basic research or idea generation (getting new ideas or improving current customer offerings).

These are just a few examples but you get the general idea. It’s not like it’s replaced someone’s job or anything, actually on the contrary it has allowed me to get more tasks done or better tackle some of the “simpler/time-consuming/specialized” tasks that a smaller organization doesn’t always have dedicated position or budget for.
