[speculative]

By end 2025 twitter will have released (at least in beta) a feature where you can generate images or other media (audio/video/3d render/etc.) to accompany your tweets, in an integrated way, where the content is related to the subject of your tweet, and optionally also includes background information about you, your appearance/avatar/profile/etc or your audience.

Example: if I tweeted an idea, it would also walk me through creation and curation of an image/media accompaniment, which might include my bitmoji within the image, and also might include specific people on twitter I like who I was atting in the thread. For example, including "@person_x" in the tweet would also lead to possibly including an image of that person's twitter bitmoji in the image, or at least in the image the person sees.

Warning: I will judge sincerely on whether something like this has happened attempting to follow the spirit of the claim - that a cool, AI media generation feature will be integrated in twitter app or website.

It can require payment, etc. It can be beta only or gated by an AB test as long as there is evidence for it. 3rd party addons don't count.
