You've phrased your question as if upgrades would need to happen often to keep up with the changing number of speeds. For reference, 10 speed shimano road came out in 2004. 11 speed came out in 2012. 12 speed in 2021. People who ride a lot typically get a new bike on a shorter timeline than that. 13 speed shimano road? It'll probably be around 2030 before the top 3 groupsets (DA, Ultegra, and 105) have moved to 13 speeds. At this point 105 just recently moved to 12 speeds, and they're not done releasing 12 speed groupsets yet.
12 speed isn't really necessary over 11, and 13 even less so for road riding on doubles. At this point it's not innovation, it's just filling one of the gaps in the cassette. The real innovation happens first in MTB groupsets, then gets trickled down to road. If it weren't for the cylcing media pretending that the number of speeds is uber important, and marketing departments wanting to be able to say "we have moar, and moar is better!" then we'd still probably be on 11 speed.
Gravel benefits more from more speeds, up to the point where lifespan dips due to cogs which are too thin to last that long. Gravel ranges have much more noticeable gaps to be filled, but you'll have to try hard to convince me that having 15-16-17-19 instead of 15-17-19 really makes any noticeable difference to more than 1% of the cycling population.

For all the complaining about the tech on cars, Id LOVE to have a CVT on my bicycle!

If you live in mountain country with steep climbs it can be a life saver, or for touring with bags. it's a good price for these.
Thx for posting OP.

Deal Editor's Notes & Price Research:
They have a non-electronic 13 speed now. My guess is 1x groupsets with 13 speed cassettes will be out by next year based on tdf preferences this year.
