So much this. I'm almost at the point of stating that echo cancellation has done more harm than good, because we are now in a situation where 80% of people have no idea that wearing earbuds could make a tremendous difference in call quality, and everyone just expects the software to magically take care of it. Sadly, the software does not just magically take care of it. Anytime two people talk, a typical echo canceler just starts decimating frequencies until both of them are unintelligible. Add in a couple of clueless teams who mount a camera/mic against a conference room wall and introduce massive amounts of room echo into the mix, and I'm at the point where a conference call becomes an absolutely mentally exhausting experience just trying to decipher what is being said. I have no hope of contributing, because I can only hear 2/3 of the syllables, and my brain is running on overdrive trying to turn those back into words. By the time I've figured out what they just said, they're half-way into the next sentence. What a stressful hellscape. Ironically, if we had no echo cancellation, it would force everyone to use ear buds, and the average call quality would be a lot better.
