DAO hack? Ethereum is old news

The interest rate is decided by the DAO. They will most probably lower it 

> effectively reversing every transaction that happened since'' This is EXACTLY what happened, you have described the fork...
No, that isn't what happened.
Only transactions related to the DAO hack were reversed. Everything else was entirely untouched. The chain wasn't wound back to an earlier block. If you had sent ETH to Coinbase, or registered an ENS name, or set up Gnosis Safe multisig, or whatever else you were doing on Ethereum back then it was totally unaffected.
> but this is publicly available knowledge.
It is, but it seems like you haven't actually looked it up?
The hard fork is detailed here:
https://eips.ethereum.org/EIPS/eip-779
ETH was taken from the attacker in an 'irregular state change', 116 addresses were impacted, no blocks were wound back, no other transactions were impacted.

Haha sure, that would have been true, but the Ethereum chain wasn't hacked, only The DAO.

> The split between Eth and Eth Classic, was an effective rollback. They split the chain at a date before the hacker had access to the funds. Hence, a defacto rollback.
Where have you got this idea from?
The term 'rollback' has a meaning, you return the chain to a previous state, effectively reversing every transaction that happened since. That is not what happened to resolve the DAO hack. It wasn't a rollback, 'defacto' or otherwise!
Only transactions related to the DAO hack were reversed, if you weren't involved then none of your transactions were undone.
As far as I remember, the only significant chain that has actually done full rollbacks is Bitcoin. Once in 2010 to remove the 184 million BTC that were created; and once in 2013 when the mining entity 'BTC Guild' wound back the chain to before Bitcoin version 0.8.

While there was no specific outage, the DAO hack led to a hard fork, which created major friction within the community. That event alone was significant and caused some people to lose trust in Ethereum.

That's wrong .. no transactions were ever removed, they're all on chain.   [Here](https://etherscan.io/tx/0x0ec3f2488a93839524add10ea229e773f6bc891b4eb4794c3337d4495263790b) is the DAO hack itself.  
What was done was a later software update was put out which explicitly transferred control of those funds to allow returning them.  The nodes that decided not to run that update either quit, or started running ETC. 
But at no point was history lost, or downtime occurred.  

So we’re going to ignore the DAO hack and chain reset because ETH was technically still running?
At a minimum, the time between the hack and the rollback should be counted as downtime given that all transactions in that time period are not in the chain.

Almost all the news I've seen from Aave lately has been related to their DAO and lab. I haven't caught anything about v4 development in an age so I'm light on details. Their tweet thread doesn't help. It's very vague on new functionality. What's the innovation here?
