Altium crashes, but is useful for routing non-trivial boards.

I last used kicad in 2014 so perhaps my opinion is dated, but there was no competition then. I can't imagine an order of magnitude improvement has happened since.

Other random thoughts: real boards take weeks because signal integrity had to be taken into account. If I can just mash wires from point to point it doesn't take that long. Also: hobbyist kicad users won't pay for this service.

No expertise necessary - who the heck is the target demographic? Who is doing custom hardware these days that finds the PCB layout part of the design difficult (but amenable to autorouting?)
