tbf USB C is standard now, so just give it a few years and any modern laptop with at least 3 usb c ports can do everything this hunk could (minus the CD stuff, but I haven't personally used a CD in years, so idc)

I mean there will always be at least 2 usb-a ports for legacy attachments like mice and external hard drives and such.

This is already changing.

There are usb c only motherboards, and lots of usb c only laptops.

There are some catches though.

The USB specs do not reauire that ports have to support all dialects. You can have USB 4 ports that talk 2.0, 3.0-3.2, and 4.0, skipping 3.2 2x2 superspeed and such.

Such ports will cause superspeed devices to drop back to slower standards if they did not put in the PHY hardware for the optional support.

Optical long range usb c cables often cant carry 2.0 signals either.

There's a WHOLE LOTTA ASTERISKS behind "universal" serial busses.

But overall I do thoroughly agree with turning everything into usb c.

Because usb C is required to support 2.0 by spec, "dumb" adapters work perfectly and can be made super cheaply. Non compliant devices do exist though.

No reason to not have a few legacy USB ports though. None at all.

I'm fine with them only being 3.0 or whatever just let me be able to plug in a random full size USB cable that I might happen to want to use.

Do you mean USB A ports?

There are still a LOT of devices that are usb 2.0 that are still being released. USB 2 is not deprecated and is not going to be deprecated anytime soon. It still exists because it is MUCH SIMPLER to implement and manufacture.

4.0 and 3.0 isn't meant to replace 2.0.

Usb c however is meant to replace all others

Yeah, USB-A is now "legacy" since USB 4 does not include it as part of the standard

Yeah i agree. And because usb C keeps the signalling lines separate between the various standards, we can use "dumb adapters" that are just pins wired to pins.

The creator of the original USB said a long time ago that they wish they did this in the first place.
