I would look forward to the next 20 years and not backward to the last 20.
The whole frontend/backend distinction did not really exist until the web. And infrastructure is definitely something that should be automated far more than it currently is. If it needs babysitting by a team of devops, you just created a lot of work rather than automating/solving it. Tedious and repetitive. It has "AI will make this a lot easier" written all over it.
So, just be ready for the ambition level to be raised for developers. Learn to build the whole system, not just bits and pieces of the system. Lean on AI to get stuff done and figure things out. It's all just code. None of it is really that hard. But it can be a lot of work if you do all of it manually.
And let's be honest, agentic tools are showing promise and great progress but they are nowhere close to independently working on existing code bases. That's not how I use them. But they are great for problem solving, debugging, prototyping, exploring some new languages and APIs, and generally taking care of more tedious coding tasks.
So, would you consider it a bad idea to get into web dev, more specifically backend and infra?
Do you think using LLMs can accelerate learning software dev and programming skills?
