Just like I don't need a fridge with a touch screen, I don't need a laptop that is so extra. When you go to the fridge you're looking for food. Nobody cares about a touch screen. Same way, I see no compelling reason to upgrade the new laptop unless you just need a new laptop.
I think your 2019 MBP is akin to a fridge with a touchscreen. IT has items that are clearly not useable, i.e., touchbar where as Apple realized their mistakes and brought back the Function keys.
You are stating that the new MBPs (which are not exactly new at this stage) are not worth upgrading and that's clearly wrong on so many fronts.
The new MBPs have great performance, better keyboards, more ports, better screens, cooler running and are faster. Every metric that people use to measure a laptop's worth, the M1 (and now M2) Macs beat out Apple's prior models.
Apple erred when they rolled the new 2016 design, whether we're talking about the butterfly keyboard, the touchbar or the lack of ports. They made those laptops so thin that that performance was impacted. I'm happy to see a better design with the M1.
