The winner of a generation can't make new designs or innovations? They don't have any incentive to improve? What?

4 shoulder buttons wouldn't exist without Sony. Without Sony we would all be stuck with 2 shoulder buttons because reasons.

By extension the switch 2 has zero innovations because the switch won the generation.  That means no innovation. 

The entire premise blows my mind.  I mean if Edison and Tesla didn't exist we would still be living in the dark?  

Realy? let's see:

Analog Stick:

Nintendo didn't even have an analog stick; it was more of an optical tracker ball using a technology that has been completely abandoned. 

It's an "interaction" that failed miserably to become standard. It was fragile, imprecise, and lacked button functionality. The design was so bad that it was abandoned. Most later controllers (including those from Nintendo) are designed similarly to the DualShock's analog sticks, with potentiometers.

The concept wasn't even Nintendo's; it was implemented much earlier by the XE-1 AP controller.

Nintendo didn't invent the concept and failed in its implementation. What more can be said?

Rumble: 
Of course, every modern controller needs a vibration attachment, right? lol

Using internal motors is a design created by Playstation. This is the design that became the standard and influenced all subsequent controllers.

Nintendo's design died, is no longer implemented, it went extinct like Neanderthals.

Super NES controller:
Yeah, playstation copied this.

Without the N64 controller, no chance the PS controller has rumble or analog at that point and they would win the generation and have exactly zero incentive to change anything. 

Controllers today would be massively different if there was no N64 controller, that gave both Sega and Sony a kick in the ass to start looking at rumble and analog, glossing over that is crazy. 

Sony would've just stuck with this SNES rip off design:

Make this black and that's your PS2 controller and if that's your PS2 controller the rest of game history is completely different.

Do you have any way to prove your point?

It seems to me that you are only capable of making baseless speculations. To say that everything originates from Nintendo, even indirectly, and that nothing would exist without them... sounds absurd.

"If the first person to do something didn't do it no one else ever would have" is such a flawed take.

If Alexander Graham Bell and Thomas Edison both died at birth we'd still have phones today.

There's absolutely no guarantee of that at all actually. 

There is no "guiding force" that just guarantees telephones would have been invented and adopted in the same way at all, society could be very different. You could have something very different. 

You can't just remove "cause" from "cause & effect" and expect everything to work out the exact same. 

The silly assertion that Sony wouldn't have a need for a new controller design for the ps2 is flawed. For starters the ps2 was a full 3d machine, while the ps1 struggled with full 3d, hence there was a need.

This thread hit all new levels of stupid.

The first analog controller was 1982 via Atari. Nintendo didnt invent home console analog, it existed over a decade before Nintendo copied Atari.

Nintendo via the switch dominated the market yet the S2 has upgraded controller features including mouse controls.  Thus the argument winners dont change controller design is flatly false.  

Heck didnt the Wii win the generation yet the Wii U was a gamepad?  

Lol, just stupid.
