Languages and their tooling ecosystems express how computing is concretely embedded and used by society. People adopt the tools to get jobs and to get the job done, whatever the "job" is. In turn the available remunerative jobs fit certain business models and markets.
The ecological landscape that prevails today is largely monocultures centered around the distortion fields of a few oligopoly entities. But not exlcusively so. You still have all sort of remnants of previous era landscape, the enterprise world stuck in its java coffin, the quirky projects of the Web 1.0 era still trusting php etc.
Massive adoption of a fresh and "clean" new thing will only happen with the emergence of a new economic reality, expressed for example through new actors. New tools that make desirable new things possible may enable such an evolution and eventually may be synomymous with it but these things don't happen made to order.
