That's right -- modern age stuff isn't as _hackable_. Especially not at the hardware level. You get an Alexa or a mobile phone or a camera, it's all just a chip on a PCB in a plastic case, not intended to be fiddled with by anybody (not the owner, not some repair show, literally _nobody_) just to be thrown away after a year or two and replaced by a new one.
It's all very sad. There is still some software component to things that's hackable, but even that's harder to do. In the past you turned on your C64 and could start write away code, average Joe Teenager needs to install some IDE and pull in hundreds of NPM dependencies from shady places just to show a hello world. Unless daddy/mommy gave them a Linux box, then the story is different.
