Author seems to hang a lot of faith on rumor. Maybe some of those rumored things will happen, but it's pretty unlikely that
all of them will happen. (I'd be OK if the touchbar vanished though!)
Apple just announced a magnetic feature for their phones called "MagSafe". What's the chance that the revived MacBook feature called "MagSafe" won't be something phone related? A charging region on the notebook seems hard to believe but stranger things have shipped.
The author is also quite dismissive of the 12" MacBook which for me was a breakthrough product. I traveled around the world with one in my bag, wrote a ton of code, and often had to check to see if it was in my bag, it was so light. I'd still be using it except it turned out one day not to be rainstorm-proof :-(.
As for the SD slot: I asked Jobs about this in the early 2000s (this was around when PCMCIA was phasing out) and he was dismissive for the same reason: "Oh, you have an SD card? Do you also use CF? And Memory Stick?" This was painful because indeed, I used all three.
The fact is the TB3 (USB4) ports are powerful enough that they can connect to almost anything a user has. I know everybody's milage varies, but for me that's more powerful than a dedicated port I only use occasionally (as FW400 was for me) or never (FW800 in my experience).
