There is a 98 per cent probability that by 2033 human referees will lose their jobs to algorithms.

How would the players cope with no referee being on the pitch?
Every player knows to ‘play to the whistle’. Other sports are already using buzzers. On top of that, the refereeing decision will be shown on the big screens. The same screens used by the VAR at the moment.
What about the technical difficulties?
The VAR and the GLT are already using a system of cameras. So just add more cameras and some computing power. They are both cheap. On the long run, non-human referees will be cheaper than their human equivalent.
How would that work in practice?
Pre-established rules, multiple cameras, confidence levels, thresholds, continuous learning and fine tuning. These are the HW and SW components of a non-human refereeing system. This is how everything would work in case of a foul:
human referees would teach the algorithm what a foul is
the algorithm will take the input from the system of cameras and will calculate in real time the probability of a foul. Or, put differently, the confidence level that a given sequence of play represents a foul
if that confidence level is lower than a predefined threshold (or in case of advantage play), the play continues. However, if the threshold is reached, the signaling system will kick in:
the stadium buzzer will sound and the play stops
the decision is automatically shown on the big screen
if a yellow/red card is shown, the cautioned player will either acknowledge the caution (if yellow) or leave the field (if red)
the system will also project on the pitch the exact spot where the ball will be placed and, if necessary, the minimum wall distance
the play will restart with a free kick from the indicated spot
the football governing body will fine tune this ‘foul threshold’ continuously (starting with trial matches, but also at the end of the seasons, major competitions, etc)
The nail-bitting moments. The anticipation of a goal. The celebrations. The supporter chants. The excitement. We all know these moments, and we all love them. Probably this is what attracted us to football in the first place.
But they are slowly going away. Time wasting and cheating are becoming the norm. The effective playing time is decreasing every season. The referees are taking inconsistent decisions. The VAR fixed some problems, but introduced others while painfully taking away the celebrations. And on top of all that, football is currently played on empty grounds.
Football is a low-scoring game. Bayern trashing Barcelona 8-2 or Liverpool conceding 7 at Villa Park are simply outliers in a sport that usually sees less than 3 goals per game. After reaching an average of 3.79 goals per game in the middle of October, the Premier League reverted to the mean and has currently 2.66 goals per game, in line with the historic average. There are very fine margins: more than 25% of the PL games end in a draw, while in further 40% of the games the winning margin is only one goal. So in a game that sees on average less than 3 goals/match and where a team rarely wins by more than one goal, every goal counts.
In fact, a goal counts so much that it can dramatically change the way a game is played. When a team is happy with the result on the score board, they can effectively kill the rest of the game. The main weapon used for this purpose is time wasting and it’s largely tolerated by the referees and even appreciated by some pundits who are pretentiously calling it ‘game management’. Of course, this strategy doesn’t always work: sometimes the other team scores a goal, and might decide that it’s their turn to ‘manage the game’. Suddenly seeing the attacking side of a team might be an exciting view. But most of the times, everything transforms into a borefest for the neutral viewer, who would rather watch the paint dry. And just in case you were wondering how effective the time wasting is: from the allocated 90 minutes, only 55 represent actual playing time. It is not uncommon to have games with only 50% effective playing time.
Then, there are the referees. They are often responsible for sliding-doors moments and their subjective decisions can effectively decide the outcome of a game: fail to award a penalty, and several seconds later, a goal is scored at the other end. VAR doesn’t help too much in this scenario: as long as there’s not a clear and obvious error, the subjective decision of the referee will not be overturned. VAR is not interested in taking the right decision, but only in determining if there was a ‘clear an obvious error’. The right decision might be different for two different referees. The referees are also primed to give a slight advantage to the home team, are often inconsistent, can get annoyed or might simply have a bad day.
But do you know what can always take the right decision in fractions of a second, is never influenced by the home crowd and is never hungry?
Yes, I’m talking about the end of the human referees. Just as the industrial revolution moved people away from agriculture to industry, the highly intelligent, non-conscious algorithms will gradually replace humans. And incidentally, referees.
To be fair, I don’t think it’s reasonable to expect 100% correct decisions from human referees in the first place. To give only one example, the overlapping offside decisions would be a nightmare for most regular people (especially when additional players are blocking the view); yet the professional linesmen take the right decision more often than not.
The referees are taking two kinds of decisions during a game: objective and subjective. The ball leaving the field of play and the offsides are binary, objective decisions that can be easily taken by an automated system consisting of several cameras, a small computer chip and some lines of code. In fact, this system is already in use: the Goal Line Technology is already telling the referee if the ball passed the goal line or not (unless a one in 9000 matches situation occurs). In a similar way, the referee could know in real-time if a player is offside or not. And the good news is, this is already happening:
Offside decisions may soon be “semi-automated” by using Artificial Intelligence to map players and make instant decisions. Arsène Wenger, who is now FIFA’s chief of football development, has said he is hopeful it will be ready for next year’s World Cup in Qatar.

The linesmen will soon be obsolete.
The subjective decisions will be more difficult to get right in the beginning. But that’s just because the human referees have to spend time training the system by feeding him thousands and thousands of videos of previous decisions. Like the two police officers in ‘The parking space‘ episode of Seinfeld, agreeing upon the correct decision in each case might be the difficult part. However, the more games the algorithm ‘sees’, the better it will get. And at some point, its decisions will no longer go to the human referee watch, but directly to the players, via an electronic signaling system.
And then, the human referees will be obsolete.
How close we are to that moment? Your guess is as good as mine. From a technical point of view, all the pieces of the puzzle are there. What is missing is the willingness to change. All the arguments saying that this move would make the game less inclusive are nonsense. That ship has sailed the moment when VAR was introduced.
So, what would be left by the humans to do? First of all, humans can (still) set up the rules of the game. The algorithm can only be as good as the rules it applies. Garbage in, garbage out – as the old programmers say. So maybe it’s time to finally agree which limbs can be offside, and what part of the arm can be in contact with the ball. Training the beast is a continuous activity, so there’s that as well. Finally, setting up the context of the games is important. Agree on the minimum effective playing time (2 x 40 minutes?) and play until that threshold is reached. Scrap the away goal rule – which provides an incentive for the teams to see the game out. Punish the cheating. The list is long.
Football is currently broken. Fixing it is not difficult — it just takes an open mind and the willingness to do it.
The people at Medium have a very interesting collection called ‘Products I wish existed‘
There you can find some interesting ideas for your next endeavor 🙂
My product I wish existed? A device that would allow me to use my mobile phone on the fixed phone line.
They did not evolve too much since the rotary phone. For over a decade we have cordless (DECT) phones, but even the ones produced this years have modest quality (to say the least) and are not that cheap.
Their rechargeable battery has a very short life because of the frequent on the charger/off the charger cycle. Their display is miserable. And if you wish features like voice message, missed call notification or ‘do not disturb’ schedule, you will have to pay the price of a smartphone. The fixed phones are slowly dying.
I would replace them with the following solution:
-a base where the landline would connect
-your favorite smartphone via an application.
Think about it!
When you’re not at home, the base would record your messages. When you arrive home and enter your home network, the base pushes the messages on your smartphone.
Then, in order to make a phone call on the landline, you open a dedicated app, and simply use your smartphone as a DECT phone.
The same app on your smartphone would be able to take an incoming call when you’re in the home network.
The base producer would have to take half of the DECT technology (the base), eliminate the crappy DECT phone, put some wi-fi/bluetooth chip inside it and make an app that would be freely distributed.
I wish this product existed 🙂
Later edit: There is other products like I800 iCreations ($249) or Panasonic’s link to Cell line. But they do the opposite: taking the smartphone calls to the DECT phone: “Link your cell phone to your home phone”. I want to get rid of my home phone and use my smartphone instead 🙂 This guy is apparently on the good track, but it only looks like a hobby, not a commercial product.
