The idea that companies invested in "safe, performant software" before AI is laughable. Tech companies have never cared about the customers beyond their effect on KPIs.
In the past the price of caring was that you were slightly slower, but it would be obvious that the delivered quality was better.
Now you'll be at least 50% slower and likely fired if you care, because caring means understanding the code.
Companies never cared, and most engineers didn't care much either, at least not directly. But a lot still cared to cover their ass and try to do things correctly the first time to reduce future work and headaches. Now that it's all just a few prompts away "Who cares? Ship it now, if it's broken we'll just have Claude fix it later."
