let's imagine that with 8086 intel went bankrupt, what if Intel x86 never existed and our PCs evolved on z8k?

Modula2 on Z8K = Sweet Dream
Sweet Dreams are made of this.

Not just a dream - even in 1990:

Z8000 avoids some of the more ugly parts of the 8086, but it shares its problems of being essentially a 16 bit machine, with the most efficient arithmetic being on 16 bit quantities and a 64k address space plus segments.

It is better than 8086 in at least having sixteen general purpose 16 bit registers vs eight weirdly specialised ones for the 8086.

But the Motorola 68000 came only six months later with sixteen full 32 bit registers, and a natively 32 bit ISA including 32 bit pointers and address arithmetic (the first chip only brought out 24 address lines, of course. The 68020 brought out a full 32 bit address bus). It was also twice as fast.

SiliconWizard:
Just to let you know that the issue got taken care of pretty quickly after I submitted the report. So that should be fixed in the next release. (I didn't get to check the patch yet.)

Modula-2 was also used successfully for chip design.

Much later on (1995), Wirth came up with Lola (and then Lola-2), some HDL based on his programming languages (Pascal/Modula/...)
