Even if they take off, they're implemented in code, so they can't obsolete developers. Similar to the existence of cloud platforms not meaning there is no longer a need for platform dev and system administrators or even basic lab techs to physically install computing equipment. It just means for a sufficiently small business that doesn't want to roll its own infra, those roles are now employed by the cloud provider rather than the small business directly. Similarly, if no-code ever truly takes off, it just means devs who specialize in small business one-off websites won't be employed directly by small businesses and will work for no-code toolchain companies instead. The result will be consolidation and probably some amount of sector downsizing or else such products can't offer any real value, but it won't result in complete elimination of human labor.
