They haven't forgotten, they were fighting a witch-hunt orchestrated by the greens. The same eco-ideologist that ruined Germany have made it impossible to properly invest in the nuclear plants in France and to ensure knowledge and expertise is properly transmitted and developed with the younger generation.
For years the message was "don't invest in nuclear, don't study nuclear, don't build nuclear, don't maintain nuclear". Now the message is "we can't even do nuclear properly", it's a disengenous argument.
What we need is a bit of future perspective: Nuclear is here to stay for the next decades (plural). Nuclear related jobs will be in high demand. Nuclear jobs will be well paying. Nuclear jobs will be safe. Nuclear formation is important, and here is money to ensure it happens. Maintenance of nuclear plants is important, it needs to happen and it will be financed. And that will lead to true expertise and safety.
