Tim's book isn't without flaws (and is now significantly dated in many of the details), but one of the core messages is to recognize we all have a choice to do something other than work 50 years at a job we hate and then retire/die. Tons of people go through life without considering any alternatives to the path they are on, or developing the self-knowledge about what they actually want, which is a big reason so many people end up so unhappy.
He also emphasizes creating repeatable systems that you can then automate with software or hand off to other people. This helps you scale your business and income, but more importantly it preserves your time for other things you value more. The blog author thinks this is somehow a bad thing, but if nobody ever realized the efficiencies of exchanging money for services then most of us would be naked and starving; a huge chain of such exchanges is needed to produce the modern miracles of cheap clothing and food that are the foundation of modern living.
Tim didn't actually retire to the beach for a hedonic 4-hour lifestyle with servants refilling the wine glass and fanning him with palm fronds; the guy works harder than most people with a new huge book every couple of years, lots of active investing, and running a major podcast almost every week. The difference between him and other people is that he's not wasting time on stuff that other people could do for him.
I'm not a "bro", but I guess I'll stand here and defend Tim's book because it gave me a lot to think about.
