Agreed, and the ease of 'assembling' various components is much easier now. Even the project in this article has very little soldering/individual components besides a few pull up resistors and some LEDs, both of which could have been on breakout boards. Everything else is just pin headers and jumpers to/from prebuilt boards.
The Heathkits and even things like the Radio Shack spring-wire 250-in-one type kits had you build circuits from all individual components: resistors, capacitors, diodes, transistors, inductors, etc. If lucky, maybe a few basic ICs like triple-nickels, op-amps, comparators. After hours of soldering/wiring you had something that did some very basic function - not a microcontroller/SBC with full programming language support and more power than a supercomputer a few decades ago.
