Please try to be serious and don't put words in my mouth. I'm actually trying to learn and have a serious discussion here.

Thanks.

What they're describing is a serious problem in modern product innovation, so maybe it is you who should take it seriously, aye?

Let's rephrase: if we are not to test for changes in user behaviour that give positive signal to progressive innovation, then what should we do? And how should we avoid the loudest voices in a room full of whiteboards creating a product that biases towards the needs of tech company and startup employees?
