Rent smart contract storage

  Interesting possibilities in 2019.   But accelerated roadmaps and timelines make sense If more developers are involved, otherwise it's a system already with vulnerabilities probably adding more because they want speed over quality. Happens all the time everywhere, but not always good thing.

  The other interesting tidbit is renting costs for the storage of smart contracts. I understand why they need to do it.  1TB isn't something most people are going to want to download as a miner or eventual staker.  But if you build a dapp and have to pay  digitalocean for the front end web  mobile app portion; then pay for gas; and pay for storj or ipfs for regular file storage; and then pay to rent space for your smart contract ...

At some point it's an expensive experiment and gets into why would anybody build real applications on it ?  Most companies and startups aren't going to benefit a ton compared to the costs of these new systems.   And it's already a challenge to get normal people to want to use blockchain and crypto.  

The bigger challenge is not everything needs to be written to the blockchain. So you can avoid certain gas like Costs.  I guess you can say not everything needs to be a smart contract.  But the more things like  state channels and side chains and JavaScript front end logic is needed, what exactly is decentralized about most of it ?
