I feel that few will have the privilege to have the time to write code by hand. And let's actually see what we are actually writing, most of the time for me its nothing novel, nothing fancy its the same old create a backend for X, fix some simple bug and stuff that are trivial for a mid-senior programmer. The harder tasks are mostly (again for us) architectural decision over the code and I am even thinking of how we can develop a system where LLM wouldn't derail on feature implementations. Anyway, what I am trying to say is that you writing code by hand may be okay for now but in the future I believe the shareholders and whoever is on top of you will want you to deliver features/fixing bugs FASTER with the help of LLMs and if you can't deliver that you will under perform. So in the end it's not what we want but what the shareholder wants. Of course if you aren't drained by this you can write code by hand in your free time. I don't want to sounds like a doomer but I believe this will be very much a reality sometime soon.
Everyone has the time to write code by hand, because AI doesn't yield real productivity gains.
It was a never a velocity problem though, rapid progress comes mainly from designing better systems and building tight abstractions not by writing using the same primitives faster
