His views are very high, he is really riding the celeb click bait videos. Curious to see how long he can make it last. He is likely making enough to live off from those. Plus he seems to have gone full influencer mode so will be getting money from those sponsored posts/trips.
His worry should be what will happen when youtube stops. He hasn't started his career away from youtube, and if youtube dies off and his influencer status has an expire date what will he do then. Degrees have less worth the older they get if you haven't built a career from graduation to go alongside having the degree. Employers will want new graduates for entry jobs, or people with experience for higher level.
Yeah, he's going to have the Ruby Granger problem where he's put all his "effort" (such as it was) into academia when that won't benefit him in any real way long-term. Then he's switched from StudyTube crap to lazy, recycled and/or stolen ideas from other influencers and done nothing but rehash the same idea over and over with more and more ads. There's no longevity in that. There's no original thought or quality on display in his content, so that's not sustainable, but he has no backup and no real experience either. BookTube won't work for him for long because he barely reads and can never come up with his own ideas; speaking entirely in meme quotes and dad jokes won't get him far.
If he'd put in the effort to make creative, technically proficient video content, there might be work ahead in video production. But nope, just lazy rehashed, low-effort garbage that nobody in a video production field would be impressed by. If he'd actually put the work into growing his stationery business to offer a wide range of high-quality, well-designed products, he might have been able to grow that into a lucrative career. But nope, again, he just let his management team of shameless grifters slap his name on a company offering a laughably limited selection of defective, cheaply-produced and extortionately-priced products, so there's no future there.
And now, like Ruby, he has his eyes set on becoming an author despite no discernible talent or genuine interest in writing (or reading, for that matter).
They're both simply too dumb, too lazy and too talentless to gain the success they think they're entitled to. If he's smart, he's been banking all that ad cash before the offers dry up.
