Also I think they are going to replace the m2.

They've been trying to replace it since like the 60s, and the most recent attempt flopped about 10 years ago.

AFAIK infantry are usually much more resilient to artillery or aerial bombardment than tanks, since infantry can weasel into holes and micro-terrain features to use as cover, and could use certain materials to camouflage thermal signatures easier than tanks - worst case scenario they can dig tunnels, which tanks cannot (yet, most of the time). ground drones or drones that fly closer to the ground could find infantry easier perhaps but would have a harder time navigating more complicated terrain than the open sky.

it wouldnt cost 20 million if it werent for MIC grifting, one of those tanks could take out a swarm of cheap drones with an autocannon burst of airbust shells. Drones are not going to replace tanks and infantry, they are simply going to change how they are built and used, and what weapons and engineering features are considered necessary. Like airplanes didn't completely remove the need for naval power, it just made aircraft carriers important instead of destroyers. it is ignorant tech hype to assume that the Current Trending Thing is going to be the be-all end-all of warfare, there is no reason to believe that. Drones are going to be a part of warfare, they are not going to replace it.

the tanks will obviously have their own drones and infantry support lol, a tank is usually not the best reconnaissance equipment whether drones are around or not. an autocannon and the electronics required for targeting drones might be an expensive initial investment, but the individual 20-30mm shells will not be quite as expensive, probably similar in cost to a mine or a grenade, especially if a hypothetical organization had a mature industry dedicated to producing war materiel (i.e. Russia), and a single gun system could hypothetically take out multiple drones, unlike an american style missile system where each shot costs tens of thousands of dollars at least. Infantry usually cannot carry weapons with the range or accuracy to target drones, but they can still recon and feed intelligence to things that can carry large weapon systems.

I definitely think tank and vehicle design will drastically change, i think traditional large cannons and heavy armor on tanks will become less important for 'frontline' military vehicles, and they will have something like a drone swarm hangar or missiles as a primary weapon system, with smaller weapons like autocannons and large MGs for emergencies/ambushes, with less overall armor and more of a focus on situational awareness and maneuverability.

like, hypothetically even an infantryman could damage a tank with handheld equipment, or even just by digging a ditch at the right place and hiding it. this doesn't make all tanks obsolete forever. tanks have excellent range compared to infantry, and can carry heavier equipment more effectively over rough terrain than trucks, and working in tandem with well coordinated infantry can respond to a variety of threats effectively, especially if equipped for the specific threats they will face. Add drones into the mix on BOTH sides of a conflict, and the tank has access to excellent aerial surveillance and even counter-swarms of its own drones to intercept those of the enemy.

Using a scenario like ukraine, where one side relies on paltry numbers of the outdated equipment of another country's already outdated and grift-laden armament industry stripped of all the advanced electronics and armor and munitions, to argue the point that drones have completely replaced tanks for all time in perpetuity, is getting abit ahead of ourselves i think. Russia still makes and uses tanks, China still makes and maintains tanks, i'm sure Hamas would love to be able to produce and use tanks if they had the opportunity and proper conditions. like sure the American tanks are overdesigned expensive grift crap, but you can still hypothetically build a cheaper and similarly effective tank.
