In hindsight, I do think the right approach is not to use calculators till secondary school (about 14~15 years of age). Having a feel for numbers and how they should behave under addition/multiplication/exponentiation and ability to mentally do two digit calculations as you said is critical, and should be an “automatic” capability

Nope, this is a common thought amongst those impressed by AI. And I can relate coz when I was in school, no one would give a good answer to why I needed to do any arithmetics without a calculator.

Ah, no, sorry about the miscommunication.

Upi is massive in India. Big to the point that not having access to it is more than an inconvenience, it will be like Microsoft going down.

However, it is technically a protocol with federated servers and apps. Hence, there’s no single point of failure.

I meant to say if a crucial system with a single point of failure had no alternatives, it would have been scary.

Thank you, I’ve been wondering what’s going on

Ah right, that makes sense. If it were like upi or pix, and had single point of failure, it would have been scary.

Lol, did you miss the ios 26 update?

I think they meant that the single app by all banks can go down through backend crash, buggy/malicious app update, etc.

Thought you all are exaggerating until I saw Nvidia’s official demo video. Holy crap.
