I get the point you're making, but the reality is that there are several other kinds of mic technology* which are already used in other industries. MI hasn't embraced them all (yet) because they don't offer any practical advantages over the current tech... but the advances in DSP is already changing that with things like HOA and phased-array systems.
And there is definitely more than one type of speaker technology.... :think:
If you want genuine innovation, look at what is being achieved in film and video.
Sure... there is some very impressive stuff coming through... and it's because there's been seriously big money floating around in the Film/TV industries for decades now. Audio is and always has been the very poor cousin... but even so advances in DSP and AI will be trickling through. It won't be long before a single mic system, will be able to identify, capture, and isolate individual sound sources performing in the same space at the same time. We already have amazing good voice-morphing... More will come in the not-too-distant future.
Digital speaker and room correction has raised the quality of speaker tech considerably in recent years, but it would be very nice if someone came up with an altogether better technology platform.
But I wouldn't describe the MI industry as being entirely stagnant... :D
*Beyond the familiar ribbon, moving coil, electret, DC-bias capacitor and RF-bias capacitor (oh wait... that's five not four!) we should probably ignore the prehistoric and low-quality Carbon Button and Water microphones... But piezo mics are still a valid option in many applications, and the MEMS capsule already dominates the smart-tech market. There are also several variations on optical mic technology, and the Microflown (thermal) mic system -- which are already used in other industries. And then we have Ambionics and Higher-Order Ambisonics (HOA), and multi-capsule DSP-based phased-array microphones which have only become practical and cost-effective with the advance in DSP tech...
