Ethereum 2.0 splits the chain into 64 different shards. How is the state growth managed so that nodes can keep an entire copy of the blockchain and all shards?

Ethereum currently grows at 15 million gas per block, so this is a proxy to measure how fast the chain is growing in GB. If Ethereum Devs were to increase the block gas limit to 150 million for example then we could see ethereums chain growing in GB at 10x the rate.

How is sharding effected by this? If you split up the chain into 64 parts and have each validator store the entirety of the information contained within each shard, and then observe in a few years for example that user demand is filling all shards to block limit capacity, doesn't this mean that the blockchain will grow at 64x the speed and therefore require that node runners have the hardware to cope with this state growth?
