If you can build a Dyson sphere the idea of needing particular elements is probably irrelevant too. Assuming they aren't all electronic intelligences living in a virtual world, they could probably just convert bulk matter into whatever they need.
- ncmncm 7y agoStrangely enough, controlled fusion of light elements is overwhelmingly easier than constructing nuclei to order, which itself is overwhelmingly easier than creating atoms from pure energy. In any case, you need the energy. So, copious supplies of frozen light elements will be useful for much longer than one might imagine. Electronic intelligences living in a virtual world will depend on a reliable supply of both energy and computing substrate. There again, extreme low temperatures are beneficial to reduce signal noise and spontaneous decoherence.
