The computer or the computer chip is the coolest invention ever invented. Think about this. In the ancient times it took some mathematician weeks or months of dedication to calculate pi to 20 decimal places or something. But in 2021 I could calculate some weird number like pi^pi^pi to the precision of 100 000 digits on my smartphone. And it took three seconds. Think how cool that is. Technology is so advanced it's even an overkill a little bit. The smartphone is probably more powerful than all the computers in 1960's combined.
