And 'people with credentials' also believed in hydrogen cars and wide deployment of synfuels for automotive. There are lots of claims made over the last 20 years by people with credentials. But I guess you still believe in hydrogen cars so its probably not worth having this debate.
Wind and solar are replacing fossil fuels (or in the rare case of Germany, nuclear). Hydorgen cars by the time they could finally come about would be replacing already carbon free battery cars.
Hilariously enough is not only are you holding on to a relic of the past, you are also defending a technology that is far less energy efficient and is not even green, and wont be for many decades.
You can't just declare something progress because it has always been progress. Its simply a technology that has already been overtaken by something far better before it was ever deployed. That is really progress. What you are doing is declaring something the future and then holding on to it forever and claiming that its the only possible progress.
So in reality you are the one not actually looking to progress, but defending historical idea of progress.
You have a source from where you heard about it, but if you open up the link the person simply states this as fact. They do not back up their claim with any facts or sources, they simply say it.
The onus is not on me to provide counter evidence for an unsubstantiated claim. The onus is on the person making the claim to provide evidence backing it up.
No, that considered an appeal to authority.
