I honestly expected that there would be more competition entering the memory market by now. I know it takes a lot of time and capital, but Europe has plenty of semiconductor know-how with ASML and ARM, and a strong desire to be less dependent on other parts of the world, so investment in a European semiconductor industry would make a lot of sense to me. And these high memory prices sound like the perfect opportunity.
It takes too long! It's like all the people going "why don't we just build nuclear", without looking at the construction times of recent plants.
