https://www.jeremyreimer.com/rockets-item.lsp?f=true&p=272 makes it sound like the "crazy shit over the last few years" wasn't rue.
The post makes a strong case that the cataracts story and the losing his house story were false, among others.
If you're wondering why someone would make things like this up, it appears that they were cover stories for his Mineserver Kickstarter never shipping despite him saying "[i]n terms of development, this project was almost finished before the Kickstarter campaign began", "[a]ll these Mineservers will ship this week. Software is complete and SD cards are being duplicated. T-shirts are being printed every night", etc.
If it sounds unbelievable that someone would make these things up to have something to blame for a failed kickstarter, I recommend reading the post. The evidence against the house burning down is hard to argue with (later Google Maps/Street View imaging shows no apparent damage, in a later post he accidentally revealed that he used the exact laptop that he said he replaced because it was lost in the fire) and there's even stronger evidence that a number of his other claims are fabricated.
I used to read his articles back a decade ago. I really enjoyed them. This quote from the article resonated with me. It’s a sobering feeling having dedicated a career to the field to struggle keeping up.
RIP. He seemed to face a lot of struggles both physically and emotionally towards the end of his life.
