We have all these amazing technological resources and yet, houses are still out of reach for like half the population.

Does my key fob have more computing power than the Lunar Lander? In this episode of Runtime Arguments that just dropped today, Wolf and I dive into that question and we reveal some information that might surprise you. We had a lot of fun doing the research and we hope you enjoy it. Find it wherever you get your podcasts. And, if you enjoy it, please tell all of your friends. We'd really appreciate it.

TL/DL: yes, it does, and by significant amount
Key fob has nRF52840l, 64 MHz ARM, 1024 KB Flash, 256 KB RAM
Apollo Guidance Computer was 2MHz, ~72 KB ROM, ~4 KB RAM
The comparison might be up to 10x different due to more efficient architecture and different MIPS/MHz ratio, but it does not change much, since the differences are so dramatic.
(This is based on links in the podcast description, which I assume what they talked about. Those pretty new keyfobs, older ones might have something like nRF24LE01, which is only 16 MHz, 18 KB Flash, 1KB RAM)
