Although FTX was a crypto exchange the crimes committed were not dependent on blockchain technology. FTX is a company and was holding money and assets for its clients. It's somewhat similar to what Bernie Madoff did to his clients, before crypto was relevant.
Blockchain based cryptocurrency isn't going anywhere anytime soon. This will remind people to take self custody of their crypto and not leave it on an exchange.
Just like cash is a crime magnet, so is Crypto at rest, and for the same reason.
If anything, Crypto is easier to track and stop the looting, compared to if someone left a key to a warehouse containing a billion dollars in cash in it with no security cameras, which is what FTX seems to have managed to do.
I don't know if I'd consider this a fair evaluation.
From my observation, the overwhelming majority of failures, collapses, and hacks have had a fairly limited exposure to the Ethereum-style/Solidity-based networks. This even includes the exchange collapses like FTX.
By and large Monero, Litecoin, Bitcoin, Algorand, Cardano, and the other networks that are reasonably isolated from the ETH/Solidity space have been largely unaffected by the majority of the "cataclysm" that the space has seen over the last year or two. I don't see any of these projects closing up shop in the near future and I don't see their communities giving up on them either (maybe with the exception of Bitcoin's refusal to move away from PoW or to introduce more programmability).
Odds are the cryptocurrency space is going to recede for at least a few years once the ash settles but IMHO there are too many projects that have yet to suffer serious thefts (as in actual loss not numbers go up/down) in their communities. Likewise these projects tend to also be the ones with shops that are holding sufficient operating funds in stable assets (i.e. US dollar equivalents & bonds) to continue development for the next 5+ years.
TLDR: The failures, hacks, collapses, etc have had limited effect on a lot of projects outside of the popular/flashy part of the the cryptocurrency space. Those projects still have a more or less assured lease on life for the next half a decade.
