The exact same argument could be made for somebody using an NE555 instead of discrete transistors to blink an LED, or discrete transistors instead of vacuum tubes to blink a neon glow lamp. For that matter, I might call somebody a slacker for blinking an LED with an NE555 instead of an LM3909. But LM3909s are no longer manufacturer or stocked. An NE555 only costs $.50 vs. about $1 for an ATtiny, but these days, folks under the age of 40 are a lot more likely to have an ATtiny (or more likely, an ATmega on an Arduino board) sitting on their desktop. -- Mark J.
