IMPORTANT: Starting in 1.19.3, mobs no longer spawn on scaffolding. In this case, just build the spawning platforms with top slabs instead of scaffolding. The central signal tower of observers, dispensers, scaffolding blocks remains the same.

A mob farm design that is optimized for ease and speed of build while remaining expandable to up to 18000 drops per hour (in 1.16 and 1.17) in a single tower (25 platforms) without digging a perimeter. * In 1.18+, the farm produces 13500 drops per hour (including 3000 gunpowder, 2700 bone, and 2000 string per hour). Jungles are much easier to find in 1.18 and are commonly located next to deserts.

FINDING BAMBOO
Bamboo can be found in jungle biomes and in shipwrecks. In 1.18, jungles are far more common and are often located next to large deserts. Pre-1.18, you can search for a jungle biome by following the coast of an ocean in a boat or by "water skiing", which is a superfast swimming technique:

Stop by any shipwrecks that you see along the way. Underwater shipwrecks can often be seen more easily at a distance because the distinctive shape of the ship offers contrast against the distant underwater background. For example, the outline of the bow can can be seen at 0:31 to
0:35. Bamboo might be found in the supply chest, which is located right behind the mast near the bow of the ship:

You'll need to search 6 or 7 of these chests on average before finding bamboo, and not every shipwreck will have a supply chest. Still, odds are that you will find bamboo in a shipwreck before you come across a jungle biome, as not every ocean will have a jungle coast, so following the coast of just one ocean does not guarantee that you will find a jungle.
Dolphin will also lead you to underwater chests if you give them raw cod or salmon, but the chest may be that of buried treasure or ocean ruins, and not necessarily that of a shipwreck.

STOPPED MINECARTS
Some mobs may survive the fall and stop the hopper minecarts temporarily. However, mobs avoid standing on rails, so the interference tends to be brief. A mob that falls next to a stopped minecart will restart the minecart, and if either minecart is moving, the other will be restarted as well. Inside the rail loop, place a turtle egg on top of a fence post (or wither rose or sweet berry bush) to lure zombies away from the rails (see screenshot in Note 4:30 below). There is enough spare capacity in the collection system to address any brief backlog of drops.

NOTES
0:05 This basic farm produces up to 3300 drops per hour, but operates at that rate only at night.
3:20 The explanation in the video is a simplified version. The 3 pulses visible from the redstone lamp actually corresponds to a series of changes in the flowing water.
4:30 The 92.5% collection efficiency can be improved to 98+% by placing soul sand under the rails and also replacing any block next to the soul sand that is adjacent to 2 rails:

Soul sand prevents items from "splattering" when a mob dies from fall damage. Alternatively, a 5-wide diamond frame of hoppers will collect over 99% of drops.
4:58 If building in a desert, be sure to double check the biomes in the area of your build, as the beach biome will look very similar but produces zombies instead of husks.
6:29 Shut off the clock first, before working on expanding the farm.
6:49 Extending the roof out to 25 blocks from the center technically would be best for spawn rates to take advantage of all pack spawn possibilities, but the improvement is tiny for a lot of material and effort.
7:09 The optimum delay is probably 14 repeaters at full delay, instead of 13, but I kept the design at 13 to keep the layout of repeaters simple.
7:28 The powered rails are 9 blocks away from the trapdoor, meaning that there are 8 blocks in the space between the trapdoor and the powered rail.
7:44 This is a hopper minecart unloading system, not a "hopper unloading system". You may not need to install the unloading system at all if you don't afk for long.
8:33 A pillar from the roof to AFK point, like at 3:12, is technically better for spawn rates than using a bridge, but the difference is not practically noticeable.
9:14 Lava flows down at 1.5 sec/block, so it takes a little over 3 min for the lava to reach the ground.
