Well, 10-20 years equals one human generation (the time it takes a baby to grow to sexual maturity).

With Canada, you can sort of map the changes, starting with the change of flag from the Red Ensign to what looks a lot like a generic corporate logo, PETs "multicultural mosaic" and the utterly unnecessary switch to metric in the 70s, the change of Constitution in 1980, the Singh Decision in 1984, the rescinding of the Baby Bonus followed almost immediately by mass immigration being a thing under Mulroney (who distracted everyone from that with his rousing the hornet's nest of Separatism, and the GST and dancing with Reagan) .....

In the 60s and 70s, big tech was actually probably a lot bigger. In the USA, you had Ma Bell before it was broken up, and, well, Canada still runs more or less on monopolies (based on who used to be the local phone provider - Bell Canada in Ontario, for instance, or SaskTel, NorthWestTel in northern BC/Territories, and what is now Telus - but there's also Rogers and Shaw now. We've always had the most expensive phone/cell phone bills in the world ... I would say that cell phone adoption was slower in Canada than most other places because of the ridiculous prices they used to charge.)

You also had RCA, and Zenith .... and a lot of other things that were American/North American based. But now you have transnational superconglomerate corporations that are unlike anything human society has ever seen, and is a sort of structure you usually only see in eusocial things like ants and bees. But it's certainly the end result - or part of the process - of all the "growth" and the collection of massive amounts of resources. It's basically part of the evolution of an out of control technological species, but lord knows where that evolution is going to lead next. Either space, or the next mass extinction that will take humans with it, after humans are done converting the Earth's waste back into plant-usable carbon.

Do insects and bacteria play? They sent a slime mould through a maze .... and then there's the cephalopods. So I wouldn't put anything past anything. The trick is, recognizing things for what they are. But hey, in the space realm, we have Avi Loeb ... (and hey, if we send out probes, for sure a nearby, more advanced civilization might have that idea, too, and be better at it. And hell, they've found planets literally everywhere since they found the first one only, what, 30 years ago? We could be lousy with probes, but we just aren't seeing them/don't recognize them, because, really, we just started looking beyond our own human asses.
