Recall Tesla's "Battery Day" in 2020, when in he promised battery manufacturing with a process cutting costs by 50%. That production target is far from being achieved.

And let's not forget that Tesla has declining sales. In Europe, it is described as a bloodbath.

I suspect he is getting desperate.

Things are moving faster than you think. Several countries are investing heavily in SMR projects. There are 80 commercial designs underway. Russia has put out working floating SMRs. The British government has chosen the Rolls-Royce design, which is intended to be licensed to the United States, and six reactors will be exported to the Czech Republic by 2033.

EDF is the state-owned French builder of nuclear power plants, but your claim is not true.

Germany has closed its nuclear power plants and is unlikely to build any new ones. Austria and Ireland are unlikely to build any.

However, European countries have a very divided attitude towards nuclear power.

France, with 57 reactors, wants to build 14 new ones and has brought together a variety of EU countries for an alliance. The UK has 11 new reactors in the pipeline. Belgium has lifted its nuclear ban and wants to extend the life of existing reactors. Spain is in similar discussions. Italy, which closed their nuclear reactors, has decided on new ones. Both Sweden and Finland and want to build new ones.

Other countries that are considering are, besides Australia, are Denmark, Sweden, Norway, Finland and mentioned in the article Spain, France and the UK.

As I understand it, and I am not a psychiatrist, is that social media triggers the release of dopamine, which makes people feel good, but excessive use is addictive and leads to lack of concentration and sleeping problems.

Erik the Red was a Norwegian. In the 13th century (12xx), Greenland became an official part of Norway. And in 1380, Norway and Denmark entered into a union that allowed Denmark to be ruled directly from Copenhagen. The union was the Kalmar Union, consisting of Denmark, Sweden (including Finland), Norway and its colonies of Iceland, the Faroe Islands, Orkney and the Shetland Islands.

Vikings lived in Greenland until around 14xx, and the reason for the declining population is debated by historians, but is likely due to several factors, such as falling temperatures that made travel difficult. The remaining Vikings left Greenland possibly for Island or Norway, but could have lived there until 1480.

And later in the 17th century, Europeans tried again, when Denmark declared Greenland a Danish colony in 1721.

The Norse Viking Erik Thorgilsson, called Erik the Red probably due to a red beard, settled Greenland in the 970s.
His son was Leif Erikson who became the first Norseman to explore the land of Vinland, i.e. coastal North America, way before Christopher Columbus.
A statue of him was erected in Chicago in 1901.

This discussion is no longer serious on your part, so I'll stop after this. For the sake of potential readers, if there are any, I'll answer a few points, though.

REE are used in modern wind power. They make electricity production more compact and efficient, and reduce maintenance.

There are two types of wind turbine generators, the older geared wind turbine that requires a gearbox to get the speed up to 1000 rpm, and then the modern direct-drive wind turbine, with a simpler design and strong REE magnets, and no gearbox. Note also that replacing a gearbox is difficult, expensive, and often has to be done in a remote location.

For dysprosium, take a look at several ScienceDirect articles (free access to full-text scientific and medical publications) such as:

The increasing use of wind power technology and its potential for future electricity generation has stimulated a number of studies evaluating the technology in terms of capacity factor, installation and maintenance costs, environmental impact, and the availability of resources, primarily neodymium (Nd) and dysprosium (Dy) required for direct-drive wind turbines

Regarding rare earth elements, neodymium, praseodymium and dysprosium, are the ones that are required at a higher level (Huber and Steininger, 2022) as neodymium and praseodymium are used to improve the resistance of wind turbines, while dysprosium increases their resistance to demagnetization.
