The skills we needed before are just no longer as relevant. It doesn't mean the world will get dumber, it will adapt to the new tooling and paradigm that we're in. There are always people who don't like the big paradigm change, who are convinced it's the end of the "right" way to do things, but they always age terribly.
I find I learn an incredible amount from using AI + coding agents. It's a _different_ experience, and I would argue a much more efficient one to understand your craft.
Using AI as just a generator is really missing out on a lot.
I always use the calculator.
But, because the numbers that get returned aren't always the right numbers, I try to approximate the answer in my head or with paper and pencil to kind of make sure it's in the ball park.
Also, sometimes it returns digits that don't actually exist, and it's pretty insistent that the digit is correct. If I catch it early I just re-run the equation but there is a special button where I can tell it that it used a digit that does not actually exist.
Sometimes, for complex ones, it tells me it's trying to calculate and provides some details about how it's going about it and keeps going and going and going, for those ones I just reboot the calculator.
Also, the calculator may refuse to process certain operation deemed to be offensive or against the interest of the corporate-state.
Not to forget, the calculator consumes so much processing power that most people are unable to run it at home, so you need a subscription service to access general-purpose calculation.
LLMs are able to ingest numbers. And not just Arabic numerals; Did you know that there are other kinds of number systems?
Believe it or not, they also ingest multimedia. You don't need the English language to talk to a language model. Anything can be a language; you can communicate using only images.
And for that matter, modern LLMs are great at abstract math (and like anything else the results still need proofreading).
Strongly suspect this is sarcasm, but if it isn't, I applaud your... gusto? Or whatever it is you have going on here.
