He should have spent more time in rehab and less time hoping that God would to magically take care of it. The time to work on his arm was years ago shortly after it happened. His arm is dead because Jack is lazy. Nothing will bring back substantial use to that limb now. I am still amazed that someone could have a serious medical incident and just let a limb die because of sheer laziness.
If this happened to me, I'd be on the phone making rehab appointments before I even leave the hospital bed. I suspect most would be doing the same thing.
And you're right, this belongs on Tech Time and not the main channel. He uploaded the same video to that account, but he shouldn't have put in on the main channel too. He really should have just made a meta channel in the beginning to put Jack on the Go videos, his pointless stroke vlogs, his religious videos, etc. Instead he has a half dozen dead channels with content scattered all over YouTube instead of two.
Tech Time has been pointless since it's inception and shouldn't have been created. There are thousands of better tech channels, and Jack never had the competence or work ethic to be competitive with them. I weirdly follow a bunch of tiny, insignificant tech channels that essentially get no views, and all of them are better than Jack's. (Tiny tech channels weirdly fascinate me because you have a lot of really passionate, eccentric weirdos that churn out content for no particular reason.)
