Dedicated monochrome cameras and air purifiers - unnecessarily exorbitantly priced products that can be implemented for much lower price

Particularly true for dedicated black-and-white [grayscale] cameras. Despite the basic premise being so simple - the use of a monochrome sensor rather than a color sensor - the models available on the market are all horribly expensive, whereas the regular, colored cameras start at throwaway prices. It isn't like monochrome sensors are costly - several Huawei / Honor smartphones over the years have incorporated a monochrome sensor as part of the multi-camera setup. The real reason seems to be companies' desire to milk people as much as they can. Same with dedicated air-purifiers. Regular ACs installed in homes already have almost all the components that comprise an air-purifier - motors, casing / housing, control board, wiring, fans, etc. The only thing that needs adding is fortification of the dust filter inbuilt into the air conditioners. The basic point here is that at least for some products, prices are unnecessarily high, when the core feature / functionality of those products can be implemented for a much cheaper price.

What will happen to Huawei, MediaTek, Samsung, etc., if Qualcomm acquires Arm Holdings [COMPACTIDEA]

The ARM-based chip businesses of these Qualcomm rivals could get in jeopardy overnight if Qualcomm one day acquires Arm Holdings. This is not a small risk. License fees could go up dramatically. Latest designs could be given late. And so on. This is a threat that the likes of Huawei must not forget - not now after all that's being done to Huawei these days. Makes it all the more vital that Huawei and others start nurturing RISC-V chips immediately, as a solid future hedge against any kind of sanctions, blacklisting, takeover or other political restrictions. Owning the complete stack, and especially those vital parts which are ultimately under the control/ownership of hostile nations such as US and UK is critical for survival and growth.
