YOU NEED TO BECOME A FULL STACK PERSON

Summary from the TLDR newsletter

Work is much messier today than when roles were somewhat rigid and handoffs were clean. Loops are now tighter, and the fast path from idea to impact crosses multiple disciplines. It is now better to have cross-domain fluency along with product sense and engineering craft. AI doesn't lower the cost of choosing the right thing, shaping it well, and operating it in the wild. Models can accelerate execution, but developers still own intent, architecture, and accountability.
