No. It is not a reboot. It's simply a new show in the timeline that takes advantage of modern technology to show us all the cool stuff they couldn't in the 60's. Does anyone actually believe that TOS would have used velour and cardboard if it was made in our era? That is the best they could do with the money and the tech they had available, and it still managed to look very cool.
We get so hung up on "reboots" and other hot-button issues that we allow ourselves to pretend that colored blocks of wood were really computer disks and that anything that doesn't use a colored block of wood is a "reboot."
Blame it on the Episode Relics, and a little on Star Wars.
Agreed. Star Wars fans have come to terms that computer technology in a GFFA, voice synthesis is high tech so most computers even with AI, just go "beep beep boop." Personal weapons fire bolts of energy at about the speed of a slow pitch baseball. Military tactics are a mix of Napoleanic Wars and WWI biplane duels. A galactic civilization has had something like 30,000 years to improve itself and still fights religious wars, some of them involving "beep beep boop" drois. and they never quite make it out of their Galaxy. Wierdly enough, they haven't even mapped the whole place yet.
Visually though Star Wars is very coherent, thanks to the original work done on it, despite its idiosyncrasies, people find the look of it works well enough, possibly because it is understood that starwars IS set in a moribund Galaxy that can't get its act together and probably never has. Abrams didn't change anything visually when he took that helm. Yet he did with Star Trek. And Discovery clearly has elements of the Abrams movies in it, though not necessarily in the interiors.
Star Trek promises development and growth based on technology. Federation types wouldn't be so saintly if they weren't enjoying an economy without lack of resources, but no matter. It's understood things should look more advanced, and that changes over time, as do the social norms of the time periods in which the shows have been made. As much as I like them, I suspect if episodes like
Relics, A Mirror Darkly and
Trials and Tribbleations had not been made, a lot of these arguments would not be going on as strongly. Unfortunately those episodes, loveletters to the past, cemented the idea that the painted plywoood and blinkenlights of the TOS sets were "canon", whatever canon even means now.
If Shakespearean theatre admirers were like trekkers they'd riot any time the plays were shown outside the Globe or if female actresses were used.
