Well, yeah. Moore's "law" is subject to the actual laws of physics, and the linearity of advances in transistor density over time is due to humans making it so - human chosen targets for each next generation, but as we come up against the laws of physics and cost of battling them then of course this linear trend will become an asymptote.
Clearly what is driving advances in compute nowadays is not single-chip transistor density but instead multi-chiplet datacenter processors and much higher level multi-chip connectivity such as TPU pods and AI datacenter designs.
