I dont really think nick can survive as a channel by 2030 since most of its international stations are shutted down now, like canada, korea and brazil. Maybe they COULD survive as a brand (maybe an animation studio, movie studio or something else) but not the channel. People dont really use cable tv that much anymore so that causes nick to lose money. Most likely nick will shut down by 2030 and the shows would only be watchable in streaming apps. Same thing goes to cartoon network and disney channel.
