My tinfoil hat theory is that Cursor deploys a lot of “guerilla marketing” with influencers on Twitter/LinkedIn etc. When I tried it, the product was not good (maybe on par with Copilot) but you have people on social media swearing by it. Maybe it just works well for specific types of web development, but I came away thoroughly unimpressed and suspicious that some of the “word of mouth” stuff on them is actually funded by them.
