As anyone that isn't living under a rock might know, the point and shoot markets are basically annihilated from existence. The professionals/pro-amateurs who care about image quality etc didn't like the Nikon 1 and EOS M.
Out of nowhere, Sony released the E mount Alpha lineup, which reached the #1 position in mirrorless cameras. They also released the Alpha 7, which was AFAIK the first full frame mirrorless (that means the imaging sensor is the same size as 35mm film. Most DSLRs used APS-C sized sensors, which are 1.5 times smaller than 35mm film). This was unprecedented because everyone thought mirrorless was basically a toy.
Both Nikon and Canon have realized their mistakes and recognized mirrorless is serious business and is the future. Nikon has scrapped the Nikon 1 line and started making Nikon Z, which is a super pro/prosumer oriented mirrorless lineup with a full frame sensor. Canon hasn't scrapped the old mirroless line but is pushing the RF mount lineup which is also full frame.
Sony was able to seize the market by being first to market by a long shot, not to mention the vertical integration from their imaging sensor division to deliver quality products. But now that Nikon and Canon entered the game with guns blazing, we'll see what happens to Sony.
One thing of note is that Sony has opened up the E mount spec and allowed 3rd parties to create lenses. As a result there's a fuck ton of 3rd party lenses (most of them of dubious quality, but some are excellent) with autofocus support, and not just from Tamron and Sigma.
It's a really interesting time to be in this hobby/profession IMO.
IDK what they're like nowadays, but Sigma has in the past had a reputation for a larger quality variance than others.
That might not seem like a big deal but it certainly is when it’s hanging off of you for a full 12 hour wedding.
That said I still have a Sigma 35mm and 20mm in my kit.
Now, this is starting to change somehow but many, me included will wait a few more years because the cost of replacing many pro grade lenses is still very high.
I got sick of the kit lens so I got a cheap used 50mm which can shoot tack sharp and I just unboxed a 90mms macro from the G series and will try it out today.
This is what makes their move to mirrorless so tricky. While adapters for the existing lenses exist and work, in the long term you would want to upgrade many of your lenses to their mirrorless counterpart. Especially, if most new lens designs are made for the mirrorless lines.
The M(240) then added the EVF, which also precedes the A7.
All of this is a bit of trivia, as most people are not aware of the Leica M series, so I thought it would add to the discussion. The A7 certainly was the first EVF-only mirrorless 35mm camera and was sold in far higher numbers than any digital M.
I hope you realize that live-view shooting was essentially turning a dslr into a mirrorless one (caveat obvious OVF/EVF differences). Canon's dual pixel AF tech is still miles ahead of Sony's PDAF when it comes to low light focusing, and video AF. Each pixel on a canon sensor can be used for AF as well as imaging. Sony uses masked pixels which limits them because they canno't mask too many pixels for fear of IQ degradation, and having fewer AF pixels limits them in low-light focusing.

Or rather, like mature businesses, they realized that they could keep making money with DSLRs and slowly milk them dry and then ramp up mirrorless and make money there too.

That's because Sony had no expertise in making high quality professional grade lenses and teamed up with Zeiss and others to help them get up to speed initially.
But the general consensus is to get rid of your old glass if you're switching to mirrorless because the AF performance with adapters is on the "it barely works enough to not call it unusable" level.
Services, yeah, Canon are miles ahead but one step at a time.
I'm a Nikon shooter, mainly wildlife. If I was starting over today I don't know which system I'd buy into.
