I mean that we cannot replace hydrocarbons. With our current level of tech or even near term the ONLY transportation sectors that we can even begin to impact will be commuter vehicle and short trip commercial. Long distance ground transport is still far out of reach, to say nothing of oceanic shipping. And that yes, rare earth mining and alternative energy production will have just as many negative effects as the use of hydrocarbons, just different ones.

Because lithium is necessary for many basic biological processes in most sea flora and fauna, and the mass redistribution of it in seawater will have large and unknown effects. And known reserves that are suitable for use in high quality batteries have not even close to doubled. Some high quality lithium currently being used for other applications such as lubricants could be shifted to the large reserves of crap lithium we've found, but it isn't nearly enough. And you know how lithium is primarily mined right? Strip leech mining, which has a huge negative environmental impact. All in service of a battery technology that's an order of magnitude less efficient than it needs to be to actually supplant internal combustion in most use cases.

Sure, raw numbers there's enough. How accessible are they though? What is the environmental impact of obtaining them? Take lithium. If we strip it from seawater, there's all the lithium we could ever conceivably need. But it's a very energy intensive process to strip it from seawater with very poor yield and it will have a large and unknown effect on the sealife in the area from which the lithium is processed from the water. So sure, there's enough material there to make the switch. But can we continue indefinitely thereafter? Will the effects of those continuances be worse than just keeping on using hydrocarbon energy sources? Still unknown. This is a straw man.

Yes, but it requires a more sophisticated AC system and you have to have a traditional system in conjuction with the floor heating. You can leave the floor heating on low to keep the floor warm and move the excess heat out of the room with the traditional air mover HVAC. In a "dumb" system this heat will just be wasted, in a smarter system it can be diverted to other cold areas of the house.

Because there is no concensus beyond genre, it becomes far too subjective. There are people who just won't consider a sci-fi or fantasy movie an overall GOAT because it isn't realistic. So about the greatest concensus you'll ever reach is that it's a great movie in its genre, and can therefore be considered a greatest movie period by those who most appreciate that genre. I'm sure there are people who consider T2 the greatest movie of all time. There are many movies who can't claim anyone as a fan of that level. But it's not going to be many people's GoaT.
