That said I also don't think the sycophancy in LLM's is a positive trend. I don't push back against it because it's not pleasant, I push back against it because I think the 24/7 "You're absolutely right!" machine is deeply unhealthy.
Some people are especially susceptible and get one shot by it, some people seem to get by just fine, but I doubt it's actually good for anyone.
Equally bad is when they push an opinion strongly (usually on a controversial topic) without being able to justify it well.
A better analogy would be a robot vacuum which does a lousy job.
In either case, I'd recommend using a more manual method, a manual or air-hammer or a hand driven wet/dry vacuum.
