Intel didn't release much of anything exciting from ~2017 to early 2021. You are correct that the delays were far longer than Intel wanted or publicly stated. This was due to bad management, poor investment in necessary equipment, firing of great engineers, overconfidence, etc. That said, at what point do we say that they are back? What is the metric you are using to judge this?
Intel had 2 generation releases in the last 8 months. Raptor Lake has at least engineering samples in the wild. Meteor Lake is taped in and taped out. So, Intel has a reasonable shot of 4 CPU generations in just over 2 years. Is that enough, or does Intel need more to be back on track in your mind?
