Taking the Mountain View, CA theoretical example from the ULTra PRT website, which outlines where routes and stations could be located if such a system existed, which method is more effective as a solution to the last-mile problem of public transit?

A) 2-4 person PRT on a grade-separated guideway

OR

B) grade-separated bikeway w/ available bike sharing

Although bicycles are not mass transit, they are less costly to use and support. On the other hand they are not accessible to the handicapped. If one or several of the high-tech companies there offered to build UltraPRT, great.

I see it as serving the same groups of people, so I wasn't expecting the two to be called incomparable. Certainly the ideas are very different, but the purpose is the same for both ideas; get people from a transit hub to a variety of destinations--destinations which are numerous, though focused in a business park (or two or three), but not focused along an obvious route for traditional PT.

Does a PRT system actually exist anywhere? Unless there is a real working system that is actually in service somewhere, its pointless to try to compare them anything.

(Airports don't count. The PRT at Heathrow is but a glorified airport shuttle).

What's special about the PRT at Heathrow that disqualifies it?

they have to be compared within a similar setting. bicycles are used by people to get around in an urban street environment. otoh the PRT at Heathrow was made to get you from the parking lot to the airport terminal (and back) after you have driven to the airport and parked your car. I believe that's all it does. they're used for completely different purposes so it doesn't make much sense to compare them at this point.

I don't think you can do that with PRT because it requires its own special infrastructure and exclusive right of way. it makes more sense to compare bicycles to light rail and buses because they all share the street. hence PRT is more similar to a monorail and not really comparable at all to bicycles.
