Well that and the fact that the Bitcoin blockchain is now nearly 600GB.

A mere bagatelle. Check the size of Ethereum.

[radlad]

If I'm reading and understanding correctly, it looks like Ethereum's blockchain is 18TB, but you only need to download about 1.1TB if pruning: https://eips.ethereum.org/EIPS/eip-4444

It's not actually pruning, the full node is really around 1TB. That 18TB number comes from old naive design for an archive node. Archive is basically cached state after each historical block. The 1.1tb full node can generate all this data by executing blocks and the current generation of archive nodes can store it around 3TB instead of 18TB.

Has anyone predicted its size over the next 100 years?

New blocks are capped at 4096 bytes (plus some metadata), figure one every 10 minutes and there's your growth rate.

It's slower than the growth of storage/$$$

[radlad]

Of course if you're buying a 14" Macbook Pro, the upgrade to 2TB will cost you $400. Or $1,000 if you want 4TB (on top of the cost of upgrading the processor to the Max chip - necessary for that option.)
