Don't worry, we're speed running the last 50 years of computer security. What's old is now new again. Already looking at poor web application security on emerging AI/MLops tools making it rain like the 90's once again; then we have in-band signalling and lack of separation between code & data, just like back in the 70s and 80s.
I totally get your frustration, it's because you've seen the pattern before. Enjoy the ride as we all rediscover these fundamental truths we learned decades ago!
