I repeat.
This type of technology is not sustainable, not cheap and cannot be grown to a global scale without worsening the problems of climate change. BAU does not work.
This is the fundamental point and what needs to be focused on.
I assert.
The sooner that we convert all forms of industrial, residential and transportation energy use needs to clean, carbon free renewable resources, the better off we will be as a society, a species and a planet. This is our only path forward.
I think this assertion of yours is dead wrong. Your path is not the only path forward. It does not lead to a solution so it is not a path at all. We must pursue options which can produce results.
IF and only if, we were pursuing these technologies you favor so much by using the capacity being developed to replace one for one fossil fuel capabilities would you have a point. But even then it would amount to trying to continue maintaining our current civilizational structure. This is madness. BAU does not and will not work. It doesn't matter whether it is fossil BAU or Green BAU.
There is simply no path forward that way. It won't even make a significant difference in when collapse happens.
We must change and stop doing what we always do.
Even if climate change did not exist we could not continue to run our civilization the way we are now. We are way past the Earth's carrying capacity (by several times) and this alone would not allow us to continue to pursue our current BAU paths. With climate change added on top of those problems BAU is out of the question.
We must stop avoiding dealing with this situation. Everyone is ruled by fear for some reason. What about taking care of the people we will give this world too? Don't they count for anything?
