The data from the March 2026 Harris Poll survey, titled TikTok Troubles: The Platform Gen Z Can’t Quit (But Doesn’t Trust), reveals exactly what the generation mourns. Forty-one percent of Gen Z say they miss fewer ads and brands. Thirty-four percent miss raw, unfiltered content and relatable opinions. A third miss the absence of TikTok Shop, and 27% miss a time before influencer culture metastasized across every corner of the feed. In other words, what they miss is a platform that felt like it belonged to them—not to advertisers, not to brand deals, not to a commerce layer designed to monetize every swipe. In short: they miss the internet before the internet noticed them and mutated into something like television.
of course this rabbit hole goes deeper, and we have a paper using this technique for string constraint solving that i’d love to derail this post into, but i’ll save that for another time. the main point is that symbolic derivatives are a more powerful and efficient generalization of Brzozowski’s original idea, and they form the core of the new RE# engine. fun fact: symbolic derivatives are also implemented in Z3 (the SMT solver) for its sequence theory - so in some sense we’re inching closer to having an SMT solver’s core machinery inside a regex engine.
