As an example, someone who's not a native speaker of English might come up with the following paragraph (generated using a second-class translation service):
Basic principle of gamification is providing of receipt of permanent, measurable feed-back from an user, providing possibility dynamic adjustment of user behavior and, as a result, rapid mastering of all functional possibilities of appendix and stage-by-stage immersion of user in more thin moments. Another method of gamification is creation of legend, history, provided with dramatic receptions, that accompanies the process of the use of application. It assists creation for the users of feeling of complicity, contribution to common cause, interest in the achievement of some invented aims.
One could then use GPT-3+ (aka ChatGPT) to rewrite the above into something closer to what a native English speaker might write:
The fundamental idea of gamification is to give users continual, measurable feedback, allowing them to adjust their behavior dynamically and quickly learn all the features of the app. Another way of gamification is to create a story with dramatic elements that accompanies the user's experience. This helps to create a sense of involvement, contribution to a shared goal, and interest in achieving the set objectives.
Ignoring the question of how good of a job GPT-3 did here, is such use of neural networks acceptable in academia? All the original ideas are still yours but GPT-3 helps you convey them using shorter phrases and better English.
Update: Since the example I've provided generated a lot of debate, here's a slightly better original text with a correction provided by GPT-3:
On enormous territory of park there are lakes, rivers, canyons and caves. Lake Yellowstone, one of the greatest alpine lakes in North America, is located in the center of Yellowstone caldera, greatest supervolcano on a continent. Caldera is considered a dozing supervolcano; he erupted with enormous force several times for last two million years. Greater part of territory of park is covered by hardening lava; in a park there is one of five existing in the world of the geyser fields.
On the enormous territory of the park, there are lakes, rivers, canyons, and caves. Lake Yellowstone, one of the greatest alpine lakes in North America, is located in the center of the Yellowstone caldera, the greatest supervolcano on the continent. The caldera is considered a dormant supervolcano; it has erupted with enormous force several times over the last two million years. The majority of the park's territory is covered by hardened lava; within the park, there is one of the five existing geyser fields in the world.
As you can see, an extremely poor text is probably a bad use-case for GPT, but a few errors here and there are well within its capabilities.
