Bitcoin’s resilience proves that security isn't achieved by hiding flaws, but by exposing code to the open market, letting it get tested by malicious actors, and continuously hardening the consensus rules.
So many hackathon programs, developers getting paid in high amount for hackathon bounty, still, there is no better security yet. I know incident like this will trigger more security measures to be practiced and implemented, but there shouldn't be when hacks happens, upgrade should be done even when things are good.
Learning from other's mistakes too is another signal for tighter security, Binance must have learnt from Bybit and bitget hacks, asks questions about the weak point and works on it because these three exchange runs on the same or similar protocols.
