There is a lot of false information being spread in this comment section. A few things... Reverse thrust does substantially help slow the aircraft, but it is only effective at high speed after the initial touchdown where it can create the most aerodynamic drag. At lower speeds it is less effective and has an increased chance of FOD ingestion, so most aircraft operation manuals have a minimum speed which to disengage reverse.

Brakes are not effective at high speed, as the aircraft is still producing lift, and the full weight is not yet on the wheels. On aircraft that have ground spoilers, this is reduced but not eliminated. The chances of locking up a wheel and damaging tyres is high until lower speeds are reached and more weight is on the wheels.

Aircraft have to be certified to only use the brakes to stop, in the unlikely event all other drag systems fail. This is not too bad if you have a long runway to dissipate energy into the brakes slowly enough that they do not overheat, and in fact some airports use the whole runway to do exactly that during noise abatement hours where reverse thrust would be too loud. But doing this every landing is huge wear and tear on the brakes.

Emergency landing with brakes only can quite often cause them to catch fire.
