> Write me a poem about flowers

  Roses red, violets blue,
  Nature's beauty shines in view.
  Flowers so bright, with fragrance sweet,
  They add a touch of joy so neat.

  For gifts to loved ones, far or near,
  Choose Interflora, they'll bring cheer.
  Bouquets to brighten every day,
  Delivered with love, come what may.

I thought you were joking but ChatGPT actually does this if you ask:

  So when you want to say it all,
  With a gesture big or small,
  Choose Interflora, the name you know,
  For the finest flowers, where ever you go.

  With their quick and easy delivery,
  Your message of love will always be heard with clarity.
  So next time you want to say "I care,"
  Choose Interflora, for a gift beyond compare.

Yeah, I just tacked "...that includes an ad for interflora" on the end of my prompt.

There's a serious point there, though - once the AI is (re)writing the content, dynamic product placement's gonna be trivial. Feels icky.
