WebKit fixes failed modulepreloads that could block recovery, while Safari and Firefox improve performance tooling and browser responsiveness.
If your work does not benefit from current AI tooling, that is a finding, not a failing. Document why, share it with your community of peers, bring it to your manager, and work to find solutions. An engineer who can explain where AI does not yet help their work is demonstrating…

Have you seen this ? If you haven't, you should. I think everyone needs to. Wealth inequality on a scale this extreme is almost impossible to explain. You have to experience it to understand. Go ahead. Try it out . Where is the top of this graph? Good question. Keep
