I think you're pointing out something true and worth mentioning, but - I'm not sure why you're comparing this to numerology. People can be interested in fun facts about numbers, whether about their digital representation or not, without any wrong or mystic beliefs. Comparing this to numerology is just combative and doesn't help get your point across (as you can see by the downvotes). Besides, going to a place where people are discussing something fun and explaining to them why it isn't really fun is just not a good way to get points across to people, no matter how valid you think they are. A much better way to approach this IMO - don't say this is wrong, give something analogous that would work for all bases, which by the way would teach people this concept. E.g. extending "do all digits appear infinitely and evenly in the decimal representation of pi" to talking about "normal numbers".
