Ask HN: Whats the last thing you saw gain market share due to true innovation?
Something that's succeeding because of it used technology in a really impressive way.
Not something that's successful because it took a already proven out idea and rebranded it or had a really good GTM-strategy.
(and if your answer is ChatGPT, then see yourself out ) The most recent thing I can think of is the smartphone. mRNA vaccine? To be fair, the technology has been around for a while, so it may not meet your criteria.
