The way Ethereum, its programming language, as well as its "smart contracts" work effectively ensures there will be an infinite amount of such issues in Ethereum's future (assuming Ethereum also survives indefinitely, despite all of these issues).

If Ethereum is the "internet," then all of these incidents are kind of like "data breaches" that have happened and will continue to happen for the entire life of the internet/Ethereum network. And if the number of data breaches throughout the internet's life is any indication for what will happen on Ethereum, there will be a lot of "hard forks" in Ethereum's future, too.

Ethereum devs signed-up for this when they decided to make its smart contracts Turing complete.
