Code is cheaper. Simple code is cheap. More complex code may not be cheaper.

The reason you pay attention to details is because complexity compounds and the cheapest cleanup is when you write something, not when it breaks.

This last part is still not fully fleshed out.

For now. Is there any reason to not expect things to improve further?

Regardless, a lot of code is cheap now and building products is fun regardless, but I doubt this will translate into more than very short-term benefits. When you lower the bar you get 10x more stuff, 10x more noise, etc. You lower it more you get 100x and so on.
