They don't know what they are talking about.

Last time I checked thermistors also were analog. Of course the subject of the video is to advertise their semiconductor based analog temperature sensors, but they completely forgot about stability, aging, and noise of those. Everything depends on the application, and there are linear thermistors available as well. The most stable temperature sensors are platinum and ceramic NTC thermistors, and of course an experienced designer would never build a circuit like that. Our metrology grade thermistor instruments are capable of less than 100 micro-degrees peak to peak readout noise, with annual aging in the order of milli-degrees - you just can't get that with any semiconductor based temperature sensor. And what about the maximum temperature? Semiconductors only survive relatively low temperatures compared to other sensors.

I do wonder how much extra it ends up costing to write that "challenging code" for a thermistor.

Thermistors are a pain to use and writing code to make them linear is always a challenge.  The problem is that they are just so darn cheap, it's hard to justify not using a thermistor.
