And if someone was like “What’s the big deal with the Tesla Model S?” I could say things like “This car runs on electricity, so it will help reduce our carbon footprint. It’s also really fast, really quiet, has more storage space than other cars, has better software than other cars.” and the person asking the question would have an answer.
What I wouldn’t do is say “Whatever, when this is the only kind of car you can buy, you’ll understand.” Which is the answer I get a lot when I ask questions about crypto and NFTs.
My reading of this is that it's describing something at a single point of time. So to use your example, the Tesla S was niche, _then_ the 3 evolved the idea to become revolutionary.
Some niches eventually become revolutionary, but they're not both niche and revolutionary at the same time.
