No, its quite possible for a language to have strong backing before it takes off (C#, JavaScript, Go, Swift, Dart, Rust all did, to varying extents, from day one) and those tend to also be the langauges that take off quickly. Other languages struggle until they attract either a sufficient mass of distributed backing or the one key backer that gives it the level of support and visibility that supports the adoption curve taking off, and most never reach that point.
