8 bits at a time, and this is still being used. 
CLEAR_RAM:
CLRA
STA RAM_STRT
LDHX #RAM_STRT+1 ;CLEAR FIRST RAM AREA
LOOP_1:
MOV RAM_STRT,X+
CPHX #RAM_END
BLO LOOP_1
LDHX #NEXT_RAM ;CLEAR NEXT RAM AREA
LOOP_2:
MOV RAM_STRT,X+
CPHX #RAM_END_2
BLO LOOP_2
CLRH
CLRX
RTS
It was broke, so I fixed it.

Ah! I preferred the Z80 version:
LD HL,RAM_START
LD DE,RAM_START+1
LD BC,RAM_SIZE
XOR A
LD (HL),A
LDIR
Real men don't use instructions. They are only the manufacturers opinion on how to put the thing together.

I'd forgotten that! 
My least favorite recalled unintentional delete was the accidental unplugging of the power supply on the 8080A trainer on the fifth to the last line of a 600 line step program to be entered.

You brought tears to my eyes (from pain!) reminding me when I had to do the hardware stuff.

Complexity always goes up, but at the same time we are heading for a singularity and simplification.

Does this comment mean anything?
Things are getting more complex, while simultaneously getting simpler? Seriously

With so many APIs now available, programming seems to have become more about knowledge about APIs rather than writing actual code.

...sooner or later, programming will be simpler to the point to be just the last step of design.
Someday, metadata based systems will "talk" between themselves to integrate and extend as required.
In the decades between, developers will continue passing from the "how" to the "what", raising the level of abstraction of the solutions they create.
Wake up! The Singularity is coming.

True. Whenever we discuss the future, we need to distinguish between one of several futures: what we wish would occur, what we thing could occur, and what will probably happen. In the short term, inertia will hold us on a narrow path of incremental evolution. When most of the control is exercised by certain big players, things will progress more and more slowly. Compare how much has changed between 1950 and 1985, and how small the subsequent changes have been in comparison.
Eventually, someone will step out of the forest and show the world the pointless drudgery of pouring gigabytes of literal code into thousands of unintelligent frameworks. They will analyze what the programmers and their programs are doing, together as a single unit, and realize that it is much like a person pulling a horse forward. However, when that day comes, it could amount to little if the market isn't ready for something new.
