Not something I'd personally invest in directly but I'd imagine this effect a wide array of businesses first of mind is content businesses such as Netflix, YouTube, Facebook and for music something like Spotify.
Made me think of an idea, imagine say AI used to create individual lending and variable savings rates based on transaction history and income streams. Better purchases and comfortably meeting expenses as they arise may lead to lower credit risk and a personalised interet rates, and may predict credit stress ahead of time for banks, as a example of application but likely only possible with a cashless based society, something we're trending towards.
Thanks for bringing this to our attention @saintex.
