I for one am quite surprised. Sometimes impressed. But also often frustrated. And occasionally disappointed. Sometimes worried about the negative follow-on effects. Working with current LLMs spans the whole gamut... But for coding we are at the point where even the current level is quite useful. And as the tools/systems get better, the usefilness is going to increase quite a bit. Even if models improve slowly from this point on. It will impact the whole industry over the next years, and since software is eating the world, will impact many other industries as well. Exponential? Perhaps in the same way as computers and Internet have been exponential - cost per X (say tokens) will probably go down exponentially the next years and decades, the same way cost per FLOP went down, on megabytes transferred. But those exponential gains did not results in exponential growth in productivity, or if so, the exponent is much much lower. And I suspect it will likely be the same for artificial intelligence.
