A broad statement such as this inevitably gets it wrong. I use micropython for developing embedded applications for industrial sensors. It is much faster to develop and I am fine using microcontrollers with enough memory that I do not need to optimize every last byte. Cost of the hardware is not the priority. There are applications where there is not enough memory and python isn't the right tool. But in a world where microcontrollers keep getting more advanced and packaging more memory, claiming that languages like Python have no place is just as wrong as when people claimed Python had no place against C/C++ back when PCs were more resource constrained. The economics for this type of question typically center around volume shipments. If you're shipping lots of hardware, optimizing hardware cost (and therefore minimizing software resource requirements) is the priority. If you're not, developer time is the main cost. There are a lot of products in the latter category.
