Are we using AI to think faster, or to stop thinking at all?

I've noticed a shift in how I work over the past year, and I'm not 100% sure it's a good one.

A year ago, I'd use AI to speed up execution like writing boilerplate code, drafting an email or summarizing a doc. The thinking was still mine. Now, more and more often, I catch myself asking AI to decide things too: which architecture to pick, how to frame a pricing page, even how to respond to a tricky customer email. The line between "helping me think" and "thinking for me" has gotten blurry.

Here's what worries me a bit: the moments where I learn the most are usually the moments where I struggle first. If AI removes the struggle, does it also remove the learning? Or is that just an old-fashioned way of looking at it - the same way people worried calculators would ruin math skills, and mostly they didn't?

Do you think AI has made you better at thinking, or just faster at producing? And any moment where relying on AI backfired because you skipped the "struggle" step?
