Love blu-rays. So much more scratch resistant than DVDs.

Yeah I still buy Blu rays to this day, as I prefer to own my movies rather than stream/rent them.
I don't have the same fondness for them (or own as many) as for VHS/DVD, but they do at least offer terrific audio-visual quality.
As long as physical media exists, I'll keep buying them.

I do often like digital copies with my physical copies and buy digital movies sometimes too.

I will say that if streaming subscriptions were niche to nonexistent then I would want the storefronts to have limited DRM where you could download everything to keep offline in case you lose access to a title for any number of reasons. Like GOG for movies. 

Happy birthday! I still buy movies and shows on disc, mostly 4K format for my favorites. It's still unbeaten in visual and audio quality - but there are certain issues; pricing, localization, hardware and compatibility issues with sound and HDR-formats, among others.

I never got around to upgrading to 4K/UHD Blu Ray, as the regular ones were already good enough for me.

Heck, up until the early 2020s I still bought DVDs if it was a movie that didn't focus on visuals, just cos they're usually $10 cheaper here.

I love Blu-Rays. Probably my favourite format for movies. Though not as big a leap as VHS-DVD (well arguably it is a bigger leap than Laser Disc- DVD, as Laser Disc is probably the real predecessor to DVD, but never gained much popularity), it was still a major upgrade. 4K UHD Blu-rays are cool, but the required set-up you need to take advantage of the upgrade makes it diminishing returns for most people considering what they still charge for the discs. Blu-rays are for the most part already so good when it comes to audio and visuals.
I still primarily watch movies on physical media, as the streaming sites don’t know what the fuck they are doing. Letting algorithms tell me what to watch is not my thing. The quality of picture and audio is not as good as Blu-rays really, and depends on internet bandwidth. Streaming sites just want power and don’t give a shit about the art. HBO MAX cut the first 5 min of 2001: A Space Odyssey, which is black screen with ambient noise. Yeah, I am happy to have the Blu-Ray.
With the authoritarian leadership in Washington, it is probably also just a matter of time before Ali Abbassi’s incredible biopic The Apprentice gets pulled from streaming and online stores, they won’t get my physical copy!
I consider 1998-2012 give or take a year or two as the golden age of physical media as far as movies are concerned. And of course the Blu-Ray entered the market right in the middle of that.

I was an early adopter, getting a PS3 early, Sony even sent me a copy of Casino Royale as I got the system early, it became my first Blu-Ray, and I still have it to this day.

Will we get another low-cost physical format again? Or is this the end of the road?

I'm struggling to picture another physical format after Ultra HD Blu-ray. UHDs are not selling enough to justify 8K Blu-ray discs.

Putting movies on SD cards or Mini SSDs as a future physical format seems very costly and impractical. 

Holographic video is next, the tech just doesn't exist yet. It depends on how fast the internet is by the time holo displays replace TVs.

Crazy it's still around.

Mid PS3 gen a new disc format called HVD but never came out.

Back when the PS4 was about to be announced I was expecting a new disc based tech to replace blu-ray, Sony pre announced a new disc format that would hold 300gb, but then only a bit after the PS4 was out Sony fully announced it as the Archival Disc, but it was delayed and not suitable to mass production due to its cost, it was aimed at datacenters. PS5 came and again, blu-ray it was.

And here we are, blu-ray has more layers and more space and it lasted 20 years.

Sony has now stopped selling blank blu-rays but movies and mostly Playstation is still keeping it strong. Even so, will it still be in the PS6? If they want to phase it out it would be a good time to do so, but then what, which kind of physical media would they pick?

Would they even spend that much money to help develop another new disc format when physical is being less and less relevant everyday?

If possible they can add another to the blu-ray and make it bigger again, so it will last even longer, or just ship bigger games on 2 discs like they already do now.

Either way, it's crazy to think how old it already is and how it's still here without a successor.
