Being 81 entitles a guy to ramble on a bit so I will.
I'll keep using Zoom, including iac lessons if they occur. From what I have seen I am more cautious than average, maybe quite a bit more so, but I do use some things. Prompted by your comment I tried to find a NYT article of a few weeks back back that looked at various remote conference options, listing pluses and minuses for each. and as I recall they decided Zoom was likely to be the best choice for the casual user. I don't recall the article in detail and I couldn't find it.
Some things are more worrisome than others, and the context matters. My daughter now works from home and this leads to remote conferences. It's a competitive world and corporate security matters. They have switched from Zoom to something else. But as for me, discussing bridge, I don't say anything important enough for anyone to uncover. Kibbing yesterday I sent a private note to someone saying I thought the bidding was weird. Well, it was. I doubt anyone wants to track that statement down and let the players know what I said.
Yes privacy is important to me. We of an age can be boring about the old days but it is a fact that when I was ten I rode my bike off somewhere, no one knew where I was and no one knew how to reach me to ask where I was or what I was doing. Yes, I think there is a lot to be said for having time to oneself, accountable to no one, at least as long as a person is doing nothing worse than stealing plums from the plum tree in the local tree nursery. Well, now we are connected, and connected, and connected. Except in my case my cell phone broke a few months ago and I mean to get another but haven't yet. And Becky (my wife) still has a working cell phone but often doesn't carry it. So there are times we actually cannot call reach other. This seems to horrify some people. It seems natural to us, old habits die hard.
Anyway, I use Google to search for things and then I get ads, in some cases the logic of how the ads followed from the search escapes me. And we all get these robo-calls. But I think I get less of this than many people do so I must be doing something right or at least not too wrong.
So I will keep using Zoom. But I also will listen to other suggestions.
