The camera industry didn't know the cellphone will suffocate them. A disruptive technology may emerge and cellphone may cause more damage. If we assume that the next decade will be the decade of mirrorless then Canon most likely will dominate the market. There are several reasons.
1. It is not difficult to understand why Canon continued with DSLR that long and didn't put all their effort into mirrorless. Canon is now serious about mirrorless. They have the money and talent to be competitive/superior in mirrorless technology. They lacked serious intention. Now they don't.
2. But it is not all about technology. Canon knows how to make great cameras and lenses which more people love to use compared to any other brand. This has to do with ergonomics, the menu system, usable LCD and ease of use. Just think about it, the best technology company can't make as good an LCD as Canon does. Most of these aspects are subjective but these have more effect on buying decisions than we tend to believe in these forums.
3. Photojournalists and other pros used to be the influencers at the beginning of the digital era (they still are). Canon dominated this segment. Now, we also have internet influencers, especially vloggers. With flip-out LCD and DPAF Canon dominated this segment too despite the fact that the most vocal bloggers were against Canon. Canon has targeted this vocal segment (as well as pros) with the initial RF lens line up. Vloggers are raving about these lenses (and other things). As a result, the number of 'Í am switching back to Canon' Youtubers are increasing every day. Here is a random one.

4. Canon colors, subjective but very important reason. All YouTubers coming back or new to Canon mention this to be one of the most important reasons for buying EOS R.
5. Outside the bubble of the forums, the overwhelming majority of people still shoot DSLR and 90% or more of them use Canon or Nikon. A very small number of them started to taste mirrorless with the release of R and Z cameras and the rest will eventually make the move. The rest don't care about mirrorless because their DSLRs just work. When they make the move over the next few years Canon (and Nikon) will be ready to take them. If Canon (and Nikon) can create the reverse 'switching back' movement with just two cameras and a handful of lenses, imagine what will happen when the system matures in 2-3 years.
6. The usual stuff like the most extensive support, reputation, name recognition, etc.
7. In these forums, we underestimate the emotional and subjective aspects of buying decisions. For these reasons Canon won't have to be #1 in technology to be the most dominant force in mirrorless in the coming decade, they just need to be close enough.
Again, read the comments too.
