Writing syntax is still an important part of the experience. It is valuable because it requires you to spend time immersed in the nuts and bolts that hold software together. I'd compare it to cooking, if you have an assistant or a machine do everything and you never actually touch a knife or stir a pot, you'll lose your touch. But there is also something valuable about covering more ground and the additional experience that brings.
But the larger scale system design is stronger than ever. Today, distributed systems, version control, including branching, stacked PRs etc., VMs/containers, idempotency, multimaster ACID databases, all of these things were probably never achievable in the world when the best devs had to spend their time poring over assembly language every day. Losing that skill allowed them more time to build other ones!
