As to SUSY, while it is good if young post docs are avoiding it, that does not mean it has gone away (not if PRD table of contents is any indicator). It will take a long time for that paper mill to end, likely with the retirement/death of current researchers or sooner if funding agencies finally come to their senses.
I don't think she is suggesting there should be no efforts in some of the other areas you have mentioned, just that there needs to be a reassessment of how much effort and money should continued to be funneled in those directions.
Plans continue because if they didn’t, starting from scratch and ramping up again would take decades. This is simply because expertise would be lost in the meantime. Just because the plans are being made does not mean it’s inevitably going to happen.
