Is that backed by any evidence? Taking 2 hours to perform a 1 hour task makes you half as productive. You are exchanging that for the uncertain prospect that it will be worth it in the long run. I think it's more likely that if you take 30 minutes to do the task in one year from now it's because AI got better, not because you made the code more AI friendly. In that case, those people taking 1 hour to perform the task now will also take 30 minutes to perform them in the future.
