I guess Thunderbolt 5 will have to wait until M5.

I do wonder if they can continue improving interconnect specs as with Thunderbolt 4 the cable seems to be already the limiting factor. It’s thick, expensive and only available in very short lengths.

100% it is an looming adoption challenge. The same problem exists with finding verified DisplayPort 2.1 80Gbps cables.

Optical interconnects might be the only way forward.

Thunderbolt was supposed to be optical originally, maybe it's time. There are rumors of PCIE 7 being optical too.
