Can the 8GB Raspberry Pi4 replace my MacBook Pro?

Spoiler alert...
No!
Mainly because communication tools we take for granted on Mac and Windows don't have versions for ARM64. This may change for two main reasons.
- Apple is slated to make an announcement that they will move Mac from Intel to ARM64 processors. More at WWDC. - Google has opened up Fuchsia, it's new capabilities-based OS for Intel and ARM64.
We surmise that polished desktop apps for ARM64 are likely to start appearing in 12-18 months.
Until then Raspberry Pi 4 even the 8GB model with 1.8 GHz quad processor is mainly for developers, hobbyists, teaching using terminal with CLI scripts. i.e. Chromium requires you bake your own Pi page

The premise of this article is a bit silly because the Raspberry Pi is not intended to replace a Macbook for most people. I personally use a Raspberry Pi4 desktop on a daily basis but only for web browsing with one or two browser tabs open, and for this narrow use case, it is a "good enough" computer.
