Imagine if Rust only did releases every 18 or 36 months like other popular languages, or every six months like OP wants. Features that haven't been fully baked would be pushed in to the current release because people wouldn't want to wait another 6 months to see their work come to fruition. When the next release is only six weeks away, the cost of saying "aight, let's take our time and make sure it's ready before sending it out" is so small. The MVP of Const generics has been delayed by 6 weeks, upsetting exactly 0 people.
Regular releases of the compiler are awesome for the same reason continuous deployment of web apps is - each release only packs a small number of features. The chances of something breaking are much smaller than if it was a massive release of hundreds of features, all of which need to be tested in isolation and then with each other. The releases page (https://github.com/rust-lang/rust/blob/master/RELEASES.md) shows how rare it is for a fix release to be made. Even when it is, it's something minor.
Making the language easier to learn is a high priority. Many people are working on this actively right now - better documentation, better error messages, better IDE experience and so on. OP has misdiagnosed the root cause and blamed something that actually makes it easier to learn the language.
