Just like the old joke: "I'm already 90 percent done, now I'm going for the other 90 percent."
Before we can finish automating this process, we just have to automate this one other little task inside.
Zeno's paradox of software development - you can complete 90% of the remaining work, but you can never be fully done.
Needs to be a sign
Not really, no. In a normal development project last 20% take just as long. But AI applications are a very special beast.
If there's anything I would not trust an AI on its polish. It's amazing for prototyping, and has some viability at scaling up an existing operation. But the rough edges (literally in some industries) are the exact reason it's such a controversial tech as of now.
