Hard disagree, at least on some content. The engineering videos where they do crazy hacks like negative cooling computers, swimming pool water cooling etc are all insightful and inviting viewers to explore hardware hacking and engineering.
I suspect techlinked troll HN for news content, but I watch that for the humour rather than news.
They put out a "crazy engineering" video maybe once every 6 months while putting out 5+ videos every single week. The majority of the videos being uploaded are them faking enthusiasm for version i+1 of whatever product giant tech company put out this week or them trashing some silly or sometimes misunderstood idea.
I never bother watching LTT anyway. It represents everything that's wrong with YouTube.
When it comes to creators I actually respect I'd think of Dave Jones (EEVBlog), Naomi Wu, Louis Rossman...
