I think one can be simultaneously excited about a big breakthrough like this, but also understand that there's still a ton more to do before we have viable fusion power.

And it's unreasonable and annoying to expect everyone to say "This is amazing, but..." rather than just "This is amazing". Yes, we know, fusion power isn't ready, and we have no idea when (or if) it will be.

I haven't been "holding my breath". I've been watching from afar, checking in occasionally (like when this sort of news comes out), and I genuinely think this particular breakthrough is exciting. I don't need the tiresome -- yes, incredibly, frustratingly tiresome -- legion of naysayers coming in and stating the obvious every single time.
