1/ After recent attacks, many complain that flash loans are evil. Yes, they're painful, but ultimately good for DeFi. With significant funds at stake, people WILL make significant efforts to steal them. The attacks are inevitable & flash loans just accelerate their timeline

2/ As DeFi TVL grows, more well-funded attackers enter the space. These "killer whales" can fund attacks without flash loans. Flash loans merely democratise access to expensive attacks to let smaller hackers do earlier what killer whales will try to do later

3/ We are building financial infrastructure for trillions of $s, and need to build safer sooner, rather than later. Flash loans force us to build better now with less money at stake. Not only individual protocols are hardened, but we learn and improve together, generationally

4/ n.b. flash loans weren't design with attacks in mind. They have much broader DeFi utility and is a key component powering many key dapps that we've learned to love @DeFiSaver @Instadapp @AaveAave etc
