<p>I think that the core of the issue is that <a href="https://ai.stackexchange.com/">https://ai.stackexchange.com/</a> and <a href="https://stats.stackexchange.com/">https://stats.stackexchange.com/</a> have way too much overlap. E.g., see:</p>

<ul>
<li><a href="https://stats.meta.stackexchange.com/q/4243/12359">After Data Science SE: Artificial Intelligence SE</a></li>
<li><a href="https://ai.meta.stackexchange.com/q/4/4">Are all questions asked on stats and data science SE also on topic on AI.SE?</a></li>
<li><a href="https://ai.meta.stackexchange.com/q/1444/4">What percentage of questions posted on AI.SE are also on-topic on Cross Validated and Data Science?</a></li>
</ul>

<p>If Stack Exchange wants create a website for each trendy name (AI, data science, etc.) without caring about how much they overlap with existing websites, then I'd suggest to implement <a href="https://meta.stackexchange.com/q/199989/178179">"crossover questions" between sites</a>.</p>
