I don't get all that either, though I don't mind if nuclear is the future we'd just need to let go of the brakes on it. The other thing to look at is overall growth of each type - China is going ham on wind, solar, hydro, and nuclear yet they've still had to increase the total amount of power generated by coal, oil, and gas anyways. Graphs always predict something like https://www.eia.gov/todayinenergy/images/2017.09.27/main.png but we really always end up with https://upload.wikimedia.org/wikipedia/commons/thumb/1/18/Ch...
Whatever the cheapest (clean) option deployable is people should be wanting to throw it in as fast as we can until we actually hit a technology limit with its usability instead of worrying it won't be able to get us to 100% or not. Instead, the conversation tends to read like we've already succeeded in deploying clean energy fast enough and we should stop looking or that we are still looking for a technology which can cut our current emissions and waiting for an answer. Neither are true, we're still burning more fossil fuels during the day. The US at least managed to hit break even growth in electricity generation https://upload.wikimedia.org/wikipedia/commons/a/aa/US_Elect... even after stalling nuclear outputs but there's still a lot to go there all the same. I'm not as familiar with Europe.
About the only stances I've been able to make sense of (even though I don't personally agree with them) are the concern nuclear is a step back rather than a step forward and that's why we shouldn't deploy it and the people that just want the cheapest power regardless of source. Everyone else doesn't seem to have a reason to worry about "what" as much as "how to deploy more" for the moment. The dirtier power tends to be the one that's easier to spin up/down very rapidly anyways - "keep the capacity for now and just run it less when you can" is still a great thing.
I'm not sure what you're arguing that's different than what I'm arguing. What I'm arguing is that renewables are being deployed on an exponential (S-)curve and nuclear is not. Given the relatively short time frame we have to solve this issue, any viable solution must exhibit this exponential deployment increase.
(This does not mean we'll succeed. Maybe we're all doomed anyway. But any approach that doesn't have this shape is a disaster.)
If you actually care about this problem, the actual question is: how do we get nuclear onto that same exponential pathway that renewables are on? Fiddling around with our existing legacy nuclear plants is so inadequate to our emissions pathways right now that it's equivalent to surrender.
