I have never said or intended to imply that there were no advances made in the last 20 or 30 years.
This would be great news if it was commercialy viable, but it isn’t. It NEVER is.
That’s pretty definite by any measure.
But I get it. 99% of the announcements go nowhere. And it’s worse if an announcement is just hype or hyperbole. However, in science we have to do the 99% to find the 1% of true advancements.
So of if your point is just that you don’t like the hyperbole, then using hyperbole yourself is not doing yourself any favour. Of course people are going to be more measured and realistic in reply to your blatant over-statements and denials.
