I don't normally try to predict out 10 years, but I'll throw a few out, with (importantly) the corresponding probabilities I'd assign off the top of my head.

Safe predictions
----------------
1. Deep Fakes will NOT substantially alter public discourse or cause a widespread erosion of public trust. (0.78)
To be sure, there will definitely be a lot of hand wringing, particularly among older generations, but younger generations will quickly adjust the same way they adjusted to Photoshop. For the most part, nothing will change.
2. Machine Learning will become widely regarded as a dead end for real AI progress. (0.65)
This is already a non-niche opinion, but by the start of 2030, it will be the consensus of almost everyone in the field, and current claims about massive progress from systems like GPT-2 will be widely seen as hopelessly naive in hindsight.
3. Chrome will still be the dominant browser. (0.7)
No other browser will have passed Chrome in market share. This doesn't mean they won't be making progress, just that 10 years is not enough time for anyone to catch up.
4. Javascript will still be the dominant language on the web. (0.95)
WASM will open up a lot of interesting opportunities and make a lot of cool technologies possible. Most web devs will ignore it, and most web coding will still be done in Javascript. Sorry, Bernhardt.
5. PCs will still be around, people will still buy laptops. (0.9)
The mass migration to tablets and obsoletion of PCs that people have been talking about forever will still not have happened. The PC's place as a non-niche, common consumer device will be reinforced by the continued rise of convertible laptops, which will make tablets less distinct and less attractive on metrics other than cost.

Risky predictions
-----------------
6. Krita (specifically Krita) will become reasonably competitive with programs like Clip Studio. (0.35)
Krita will occupy the same space as Blender, in which it will be regarded by the general public as a similarly viable, serious contender with professional programs.
7. Matrix will become a defacto standard in the Open Source & security community over platforms like Signal, Wire, etc... (0.3)
Interoperability and more open clients will cause a snowball effect. Platforms like Signal will still have better security, but that won't matter. Everyone will recommend that you use Matrix purely because it works with everything, and will have good enough security for most things.
8. Apple will swallow its pride and make a convertible Macbook with a touchscreen. (0.4)
The argument that consumers widely don't want touchscreens on Laptops will become impossible to defend. There will be a Macbook that has one, and it will probably be a convertible. The iOS and Mac OS merger may also happen, which will make iPads into a paired-down version of the Macbook, rather than a completely separate product.

Out-there predictions
---------------------
9. Mastodon will become a 'serious' Twitter competitor among the general public. (0.15)
Mastodon will not only still be around, and will not only still be usable for niche communities, it will be seen in the general, non-techy public as a reasonable alternative to Twitter, and Twitter will be forced to respond to it, particularly where younger generations are concerned.
10. Eating meat will be a political indicator. (0.15)
Currently, I can make a reasonable prediction that if you don't eat meat, you lean Democratic, but enough Democrats eat meat that I can't really make a prediction in the opposite direction. By 2030 I'll be able to -- if you do eat meat, I'll be able to make a reasonable prediction that you probably lean Republican.
