A lot of Engineers (or workers in general) love what they do, enjoy working at their company, and like to socialize with their co-workers.

Truth be told, the majority of people are not hungry self-learners that will thrive in retirement. You need to be disciplined for that - or else it's gonna go downhill, real fast.

Partial retirement is something I've seen a lot. Or people simply retiring from companies, but doing work as consultants for their last decade or two.

I never understood this argument. Don't retire if you like your job. It's that simple. The reality is most jobs that pay well are mentally exhausting/stressful so the type of person that wants to retire early isn't the type of person that likes their job.
