<< My question is, does anyone else have the same concerns? If so, what can
we
do about it?

In response to your question, i have a few ways that i try to help the
student understand the limitations of the calculator right fromthe beginning
of the class. i tell them that the calculator is a too, like a carpenter has
tools, but will not build the house for him/her.
As examples, in my college algebra classes I immediately show them graphing
of rational expressions and the "false asymptotes" and how to fix it with a
"friendly " window. Just today we graphed a circle and I explined why the
ends did not connect with the ZStandard window. I have spent time talking
about 94 pixels and friendly windows. I also showed them solver....... and
how it didn't give "all" the solutions.
My students learn the limitations of the calculator..... and hopefully will
be able to integrate their knowledge withe the capapbilities it does have to
enhnce their mathematical abilities and understandings.
The instructor must spend the time in the classroom explaining how the
calculator works....... not just how to work the calculator.
