This is incredible! The minimum impact I see is much improved chatbots and conversational UIs. Text generation libraries in the future might be like super powered printf formatting where the number placeholders are actually pplm discriminators used to force GPT-2 to add a position for text. Then the rest of the sentence prefills %s placeholders using a combination of other pplm discriminators.<p>e.g.
printf("%[budget]s %f", 654) where the stribg placeholder is generated using the bag of words discriminator of "budget" related sentences that also contain a single float placeholder (which is then replaced with your custom value).
