I think the author of this blog is not a heavy user of AI in real life. If you are, you know there things AI is very good at, and thing AI is bad at. AI may see exponential improvements in some aspects, but not in other aspects. In the end, those "laggard" aspects of AI will put a ceiling on its real-world performance.

I use AI in my coding for many hours each day. AI is great. But AI will not replace me in 2026 or in 2027. I have to admit I can't make projections many years in the future, because the pace of progress in AI is indeed breathtaking. But, while I am really bullish on AI, I am skeptical of claims that AI will be able to fully replace a human any time soon.
