what you say is true. But consider, the “cost” of going back part time is not very big. It’s not very stressful, and _greatly_ reduces long term risk.
Your take is a bit like saying in the year 2000 “i believe Apple is an amazing company, i’ll go ALL IN with my life savings”. If you’re right the you think you’re a genius. But what if you were wrong? What if apple turned out like IBM? Then you’d look back and think “how could i have been so stupid? so naive”.
