Mk, your opinion is noted.
Consider reading John 1:1-4 (which I am in agreement with as being specifically about Jesus).
It is clear that we are not seeing eye to eye on what this passage is "proverbially" speaking about or how wisdom is personified here as an attribute of the Lord creatively expressed in this passage...that it was with him from the beginning. I rather like the passage. I don't see it as contradicting the Word in any way when read as being about wisdom.
I have no issues reading this as wisdom being with the Lord from the beginning. I'm not sure why you want to turn that into an additional entity.
There is no room for this not to be about Jesus:
Proverbs 8
22 The Lord possessed (created) me in the beginning of his way, before his works of old.
23 I was set up from everlasting, from the beginning, or ever the earth was.
24 When there were no depths, I was brought forth; when there were no fountains abounding with water.
25 Before the mountains were settled, before the hills was I brought forth:
26 While as yet he had not made the earth, nor the fields, nor the highest part of the dust of the world.
27 When he prepared the heavens, I was there: when he set a compass upon the face of the depth:
28 When he established the clouds above: when he strengthened the fountains of the deep:
29 When he gave to the sea his decree, that the waters should not pass his commandment: when he appointed the foundations of the earth:
30 Then I was by him, as one brought up with him: and I was daily his delight, rejoicing always before him;
31 Rejoicing in the habitable part of his earth; and my delights were with the sons of men.
