I wouldn't bet on that either, but they're less mainstream, less respected, and most of us no longer feel a particular urge to humor them. Every passing year makes them less relevant, and more like the sort of people who believe in any other conspiracy theory or magical belief system.
We made some fundamental mistakes when it comes to the subject of why people believe what they believe. The polite and intellectual answer to that has a lot to say about evidence and reason, replication, publication, review... but that simply doesn't move most people. That isn't how most people live their lives. MOST people operate on networks of trust, because they lack the interest or the capacity to make informed decisions about many things. They don't know how a nuclear power plant works, they don't know anything about monoclonal antibodies, but they know people and places they trust. Their "smart" and "informed" social networks, their doctor, their priest, etc.
Unfortunately those networks of trust are easy to corrupt, not for everyone, but for a large number of people.
To be fair, if one includes religions this is significantly more than half the population. Add in astrology, psychics, ghosts, crystals, auras and other common 'woo' and it gets higher still. Sadly, HN is not a representative population sample. Skeptical non-believers are still a minority in the modern world.
