The Satoshi's vision for Bitcoin in the long run was widespread adoption so that with rising Bitcoin price, the transaction fees are sufficient enough for the miners after the 21 million are mined in 2140. The adoption is not quite there but the hardware for mining are getting better with time. We have about 122 years in hand before the last Bitcoin is mined. Anything can happen in that time. So, I think it can turn around with global tensions rising, corruption, banking failures, etc. The miners are futuristic in my view. That is the key to maintaining the Bitcoin network.
