Not spam at all. On many points. I'm on my iPad so I'll be brief (hate typing on this thing)
On advising he start a business. Launching a successful business is the greatest liberator. For OP's father a nice lifestyle business would provide him with security as he gets older. What happens when he is 60, 70, 75. None of these people talking about helping will hire him. That's an illusion. My statement could be wrong in this particular case but it isn't for the overwhelming majority of older engineers.
If your comment is about the link. No, it isn't spam at all. The registration period is now closed so I can no longer provide links to the content. I personally know somewhere in the range of 50 people doing this program through being a mentor for a local meetup group for members. There's an annual conference for the program. I believe the next one is in February. Sir Richard Branson will be the keynote speaker. So, no, not a scam or spam. The fact that people down-voted it or dismissed it as such is only a reflection of HN bias. I hope the OP did get a chance to consider it before this was voted down to the bottom and the registration period ended.
