As an amateur engineer due to never completing my degree, I still came to realize after a few years outside of school that building full scale I.C.'s is one of the most critical steps in grasping so very many theories of operation, relativistic quantum mechanics, and condensed matter physics as well as getting a much deeper grasp on design theory and topology. Once you have to deal with extravagant intelligence processing in anything whether it's analog or digital, understanding the mechanisms by which devices like timers and op amps, oscillators operate with at a deeper scale is fundamental for being a competent engineer. I also can't imagine anyone would want to be limited to heavy reliance on IC's with no greater understanding of how they function. *Any fool can use tutorials, kits, hacker mods etc. to get some desired results but only an engineer and inventor can create the source of those results other people seek to replicate.* This is why I never stopped learning even after I didn't return to school. *I ultimately invented a new type of induction motor that can be used to create an entirely new branch of technology because it's capable of so very many complicated processes just within itself, let alone in a larger scale circuit.* It's an induction intelligence controlled motor that will potentially change the world.
For sure you can use a microcontroller to replicate the functions of the 555-you can get an 8-pin ATtiny for example that's even the same size-but there are still applications where it's handy to have simple "dumb" IC rather than the overhead of programming a microcontroller. 555's can also operate over a wide voltage range, while with a microcontroller you generally have to be careful to keep voltages close to the operating logic voltage, typically 3.3 or 5V. This means that if you're doing something simple, like debouncing a switch or controlling a 12V servo, the 555 can still be a good option!

I was told that the IC 555 is completely outdated with the low memory CPU that are available on the market
