I don't think you'll see Pitot probes go away any time soon. The alternate systems may show up as a backup or redundancy to the Pitots, but until there are millions of hours of operation demonstrating proper operation in every imaginable condition, no one is going to trust the airplane to them as the sole airspeed source.
Pitots are really not that hard to get right - unlike TAT probes, you can pump lots of heat into a Pitot probe since you're not concerned that the heat will corrupt the measurement (mud daubers remain an issue though
)
UDT - don't feel bad. I was on the first 747 Air Force about 25 years ago while they were doing some functional tests. Shop couldn't understand why one test wouldn't pass - I told them probe heat needed to be on, so they flipped the switch to turn it on. Shortly thereafter the probes were on fire
